20 Highest-Rated K-Dramas on IMDb Ranked (2025)

Is Your Favorite K-Drama Actually One of the Highest-Rated on IMDb?

Okay, real talk — have you ever stayed up until 3am telling yourself “just one more episode” and then suddenly it’s 6am and you’ve finished an entire series? Yeah, same. But here’s the thing: not all K-dramas are created equal. Some are absolutely transcendent, the kind that leave you staring at your ceiling wondering why your own life doesn’t have a dramatic OST playing in the background. And the highest-rated K-dramas on IMDb? Those are the ones fans all over the world can’t stop talking about.

IMDb ratings aren’t perfect — honestly, no rating system is — but they’re a decent snapshot of what resonates with a global audience. So I went down the rabbit hole so you don’t have to. Whether you’re a seasoned Korean drama fan or you just finished Squid Game and you’re desperately looking for what to watch next, this list is for you.

Let’s get into it.

The Dramas That Broke the Internet (And Our Hearts)

1. Squid Game (2021) — IMDb: 8.0

Let me tell you, when Squid Game dropped on Netflix in September 2021, nobody was ready. This show didn’t just top the highest-rated K-dramas on IMDb — it became a full-blown global cultural moment. Lee Jung-jae plays Seong Gi-hun, a desperate man drowning in debt who gets recruited into a deadly competition with 455 other contestants. The games? Childhood classics. The stakes? Your life.

Honestly, the social commentary hits so hard it’s almost uncomfortable. Director Hwang Dong-hyuk spent a decade trying to get this made, and you can feel every ounce of that passion in every frame. The red-and-green color palette alone is iconic. Season 2 dropped in late 2024 and while opinions are split (hot take: I think Season 1 is still untouchable), there’s no denying this show changed what the world expects from Korean series.

2. My Mister (2018) — IMDb: 9.0

Okay but seriously, My Mister might be the most underrated masterpiece on this entire list. Available on Viki, this IU and Lee Sun-kyun drama is not a romance — it’s something deeper and more raw than that. It’s about two broken people quietly holding each other up without either one admitting it.

I literally cried so hard during this show that I had to take a day off from watching it just to process my emotions. IU, who most people know as a pop star with a bright bubbly image, completely disappears into the character of Ji-an. It’s the kind of performance that makes you forget you’re watching a drama at all. If you haven’t seen this one, please, I’m begging you — cancel your weekend plans.

3. Mr. Sunshine (2018) — IMDb: 8.8

Set during Korea’s turbulent late Joseon period, Mr. Sunshine is a sweeping historical epic that’s equal parts heartbreaking romance and political thriller. Lee Byung-hun plays Eugene Choi, a Korean-born soldier who returns from America as a U.S. Marine officer, and Kim Tae-ri is the aristocratic rebel who captures his heart — and honestly everyone else’s too.

The cinematography is so gorgeous it looks like a painting. Writer Kim Eun-sook (who also wrote Goblin and Descendants of the Sun) is at her absolute best here. Fair warning: bring tissues. Many tissues. The ending will wreck you in the best possible way. This one streams on Netflix and deserves every bit of its reputation.

Medical, Legal, and Crime Dramas That Actually Know Their Stuff

4. Signal (2016) — IMDb: 8.7

Here’s the thing about Signal — it takes the concept of a walkie-talkie that connects a detective in the present to one in the past and makes it feel completely real and urgent. Jo Jin-woong and Lee Je-hoon are phenomenal, and the cold cases they investigate are based on real Korean crimes, which gives the whole thing an extra layer of weight.

This is the kind of drama that makes you genuinely angry about injustice and then immediately turns around and gives you a moment of pure emotional catharsis. It’s available on Netflix and Viki, and I promise you will not sleep until you’ve finished it. The time-travel logic is tight, the pacing is relentless, and the friendship between the two leads across time is the emotional core that ties everything together.

5. Reply 1988 (2015) — IMDb: 9.0

Want to know the best part about Reply 1988? It makes you nostalgic for a time and place you’ve never even lived in. Set in a small alley neighborhood in Seoul, this drama follows five families and their teenage kids navigating the late 1980s — first loves, family struggles, neighborhood gossip, and the Olympics.

The ensemble cast is extraordinary, and the second lead syndrome in this show is practically legendary. (You know who I’m talking about.) Reply 1988 is the third installment in the Reply series and widely considered the best. It’s long — 20 episodes, each running over an hour — but I’ve rewatched it twice and ugly-cried both times. That’s how good it is. Stream it on Netflix.

6. Stranger (Season 1, 2017) — IMDb: 8.7

Cho Seung-woo plays a prosecutor with a surgically damaged ability to feel emotions, and Bae Doona is a police detective — together they’re the most compelling crime-fighting duo in Korean drama history. Stranger, known in Korea as Stranger Things — wait, no, Forest of Secrets — is a tightly plotted, brilliantly acted thriller that takes the corruption inside Korea’s legal system and puts it under a microscope.

The writing is razor sharp. There’s no romance, no aegyo, no chaebol love story — just two incredibly smart people trying to navigate an institution that doesn’t want the truth to come out. Season 2 is also excellent, but Season 1 is where the magic truly lives. Available on Netflix.

Fantasy, Romance, and the Dramas That Gave Us All Second Lead Syndrome

7. Goblin (2016) — IMDb: 8.7

Gong Yoo in a long coat walking through flower petals. That’s it. That’s the whole pitch. Okay, I’m kidding — Goblin is so much more than that iconic image. The story of a 939-year-old goblin (Gong Yoo) who needs a human bride to end his immortal life falling in love with a bubbly, lovable girl (Kim Go-eun) is the kind of fantasy romance that K-drama fans use as a benchmark for everything that comes after.

Lee Dong-wook as the Grim Reaper is absolutely magnetic, and his bromance with Gong Yoo might be the best relationship in the whole show — and that’s saying something in a drama that’s fundamentally a love story. The OST is legendary. “Stay With Me” by Chanyeol and Punch? Instant tears every single time. Stream it on Netflix.

8. Itaewon Class (2020) — IMDb: 8.1

Park Sae-ro-yi (Park Seo-joon) opens a tiny bar in Itaewon with a single-minded goal: to destroy the food conglomerate run by the chaebol family that ruined his life. This drama is essentially a revenge fantasy wrapped in a found-family story, and it is enormously satisfying.

Kim Da-mi as Jo Yi-seo is one of my favorite female characters in recent K-drama history. She’s brilliant, relentless, a little terrifying, and completely in love with a man who doesn’t initially see her that way. Sound familiar? The slow burn here is slow, and I lived for every second of it. Available on Netflix.

9. Crash Landing on You (2019) — IMDb: 8.7

A South Korean chaebol heiress accidentally paraglides into North Korea and falls in love with a North Korean army officer. I know how that sounds. But Crash Landing on You takes that premise and handles it with such warmth, humor, and unexpected emotional depth that it became a genuine phenomenon across Asia.

Hyun Bin and Son Ye-jin had such undeniable chemistry that they ended up getting married in real life — which honestly feels correct. The North Korean village side characters are scene-stealers, the romance is swoon-worthy, and the final episodes will destroy you. Netflix. Watch it now. Cancel dinner plans first.

Thrillers and Makjang Masterpieces You Can’t Look Away From

10. Mouse (2021) — IMDb: 8.3

If you want a drama that will mess with your head, Mouse on tvN is that drama. Lee Seung-gi plays a naive police officer who gets pulled into a serial killer case, and nothing — absolutely nothing — is what it seems. This show takes makjang energy and channels it into something genuinely disturbing and clever.

Hot take incoming: Mouse is one of the most underappreciated thrillers in recent K-drama history, and the fact that it doesn’t get mentioned in the same breath as Signal or is a crime. The twist midway through the series is one of the most jaw-dropping moments I’ve ever experienced watching Korean drama. Available on Viki.

11. Sky Castle (2018) — IMDb: 8.5

Set among the ultra-wealthy families in a luxury residential complex, Sky Castle is a searing critique of Korea’s obsessive education culture. Mothers doing everything — and I mean everything — to get their children into top universities. It’s dark, it’s funny, it’s horrifying, and it’s completely binge-worthy.

염정아 (Yum Jung-ah) is extraordinary in this, and the show’s blend of dark comedy and genuine tragedy makes it unlike anything else. It was a massive hit in Korea when it aired on JTBC, and it absolutely deserves its spot on any list of the best Korean series ever made.

12. Kingdom (Season 1, 2019) — IMDb: 8.3

Joseon dynasty + zombie apocalypse. Netflix took a swing and hit it completely out of the park. Kingdom is gorgeous, viscerally exciting, and uses the zombie genre to tell a pointed story about class, power, and what happens when rulers care more about staying in power than protecting their people.

Ju Ji-hoon as Crown Prince Lee Chang is compelling in every single scene, and the action sequences are genuinely cinematic. This is the show you put on when a non-K-drama fan says they’re “not sure if they can get into Korean series.” Works every time.

Slice-of-Life and Coming-of-Age Stories That Hit Different

13. Move to Heaven (2021) — IMDb: 8.6

I am not okay after Move to Heaven. This Netflix original follows a young man on the autism spectrum and his uncle as they run a trauma cleaning service — cleaning the homes of people who have died alone. Each episode is essentially a short story about a life, and by the end you’ll be in full ugly-cry mode wondering what you’re doing with your own.

Tang Jun-sang gives a beautiful, nuanced performance, and Lee Je-hoon (yes, him again — he just keeps showing up on best drama lists and it’s completely deserved) is magnetic as the complicated uncle. This drama doesn’t get enough credit in the broader conversation about the best Korean series on Netflix.

14. Misaeng: Incomplete Life (2014) — IMDb: 8.8

If you’ve ever had a soul-crushing office job, Misaeng will either comfort you or give you trauma flashbacks — probably both. Jang Geu-rae (Im Siwan) is a young man who gave up everything to become a professional Go player, fails, and ends up as a lowly contract worker at a trading company with no college degree and no connections in a world that rewards neither.

This drama is quiet and slow and absolutely devastating in its honesty about workplace culture, class, and the gap between dreams and reality. Im Siwan is extraordinary. Available on Viki, and honestly essential viewing for anyone who’s ever felt like they don’t belong somewhere they desperately need to succeed.

Recent Gems That Earned Their High Ratings

15. Extraordinary Attorney Woo (2022) — IMDb: 8.7

Park Eun-bin as Woo Young-woo, a brilliant attorney with autism who loves whales and processes the world differently from everyone around her, is one of the most joyful characters in recent Korean drama history. Extraordinary Attorney Woo is warm and funny and surprisingly smart about disability representation, and it became a genuine global hit on Netflix in 2022.

The whale metaphors! The “Woo Young-woo” name palindrome running joke! The romance with Lee Joon-ho that had everyone absolutely losing their minds! This show gave us so many heart-fluttering moments while also making us think seriously about how society treats people who think differently.

16. Our Beloved Summer (2021) — IMDb: 8.2

Choi Ung (Choi Woo-shik) and Kook Yeon-soo (Kim Da-mi — yes, her again) are exes who filmed a documentary together in high school and get pulled back into each other’s orbits when the documentary resurfaces years later. This drama is soft and bittersweet and full of the kind of dialogue that makes you stop and think “wait, did they write this specifically about my life?”

The OST for this drama is genuinely one of the best of the decade. Kim Da-mi and Choi Woo-shik reportedly dated in real life after filming this (similar Hyun Bin and Son Ye-jin energy) and it makes complete sense because their chemistry is completely effortless and real. Stream it on Netflix.

17. Twenty-Five Twenty-One (2022) — IMDb: 8.6

Oh, you want to have your heart absolutely shattered into a million pieces? Watch Twenty-Five Twenty-One. Kim Tae-ri and Nam Joo-hyuk play two people whose lives keep intersecting from the late 1990s through the early 2000s, set against the backdrop of Korea’s IMF financial crisis.

[SPOILER WARNING] The ending is controversial — a lot of fans were devastated by it — but I genuinely think it’s the only ending that could have been true to the story being told. The chemistry between the leads is some of the best in recent K-drama history, and the show’s love letter to the era is beautiful. Available on Netflix.

18. All of Us Are Dead (2022) — IMDb: 7.5

Netflix took the zombie genre that Kingdom elevated and brought it crashing into a modern high school setting. All of Us Are Dead is terrifying, emotionally brutal, and completely impossible to stop watching once you start. The teenage cast is phenomenal, and the show doesn’t shy away from the genuine horror of watching kids have to make impossible choices.

This is one of those dramas where you get dangerously attached to a character and then spend the rest of the episode terrified something will happen to them. The social commentary about bullying and institutional failure is woven throughout. Season 2 has been announced and I am not emotionally prepared.

19. Hometown Cha-Cha-Cha (2021) — IMDb: 8.2

Sometimes you just need a drama that’s basically a warm hug. Hometown Cha-Cha-Cha is exactly that — Shin Min-a as a dentist who moves to a small seaside village and Kim Seon-ho as the charming jack-of-all-trades who helps everyone in town. The community, the slow romance, the gorgeous coastal scenery. Pure comfort Korean drama energy.

Kim Seon-ho was already beloved before this show, but after it aired he reached a completely different stratosphere of K-drama fame. The banter between the leads is delightful, the supporting cast makes the village feel genuinely lived-in, and the OST is on my regular rotation even years later. Netflix.

20. Vincenzo (2021) — IMDb: 8.4

And finally — Song Joong-ki as an Italian-Korean Mafia consigliere who returns to Korea and ends up fighting corrupt corporations and a cartoonishly evil villain with a ragtag team of misfits. Vincenzo is stylish, darkly funny, utterly chaotic, and one of the most purely entertaining shows on this entire list.

The humor is jet-black. Song Joong-ki is magnetic in a way that reminds you why he became a star. Jeon Yeo-been holds her own completely. And the villain? Absolute camp perfection. Available on Netflix, and honestly the perfect drama to watch when you want something that’s equal parts ridiculous and genuinely excellent.

Frequently Asked Questions About the Highest-Rated K-Dramas on IMDb

What is the highest-rated K-drama on IMDb of all time?

Both My Mister (2018) and Reply 1988 (2015) frequently sit at the very top with ratings around 9.0 on IMDb, making them the highest-rated Korean dramas according to user scores. Squid Game gets more global attention, but among dedicated fans, these two slow-burn masterpieces consistently lead the pack.

Where can I watch the best K-dramas online?

Most of the top-rated Korean dramas are available on Netflix, which has invested heavily in Korean content. Viki (Rakuten Viki) is another excellent platform with a huge library and active fan subtitles. Disney+ also streams select Korean series, particularly JTBC productions. Many dramas are available on multiple platforms depending on your region.

Are K-dramas worth watching if you’ve never seen one before?

Absolutely yes — and honestly, the highest-rated K-dramas on IMDb are a perfect starting point. For complete beginners, Crash Landing on You, Extraordinary Attorney Woo, or Kingdom are great entry points depending on whether you prefer romance, character drama, or action. Most K-drama fans describe watching their first one as genuinely life-changing.

How long are Korean dramas typically?

Most K-dramas run between 16 and 20 episodes, with each episode typically ranging from 60 to 75 minutes. Some shorter “miniseries” run 6 to 12 episodes. Compared to American TV shows that can run for ten seasons, K-dramas tell a complete, contained story with a beginning, middle, and satisfying end — which is a huge part of why they’re so binge-worthy.

IMDb ratings reflect the average score given by registered users who’ve watched and rated a title. For Korean dramas, ratings above 8.0 are considered excellent, and anything above 8.5 is genuinely elite.
