  • I Saw the Devil

    1. I Saw the Devil

    Korean Movie - 2010

    10

    My favourite movie in general.

    One might expect it to be the typical revenge story but it isn't, not in the slightest. Instead of following the usual formula- the entire movie being about person a hunting down person b from start to finish and getting "justice" at the very end- this film instead takes a 'cat and mouse' approach. The heroine (and I use that term lightly) catches his target fairly early on, only to then purposely let him go in order to catch him again... and again... and again.

    It's a very long movie but I found it went by insanely fast. I was so locked in to all that was happening that the runtime didn't even phase me.

  • Kairos

    2. Kairos

    Korean Drama - 2020, 16 episodes

    10

    My favourite show in general.

    It earned it's place as my most favourite K-drama ever before it was even half way through airing.

    Right away I noticed and appreciated it's use of colour tones. When we're shown scenes in Ae ri's timeline, it has a bright yellowey colouring overlayed. When we're shown Seo jin's timeline, it has a darker blue-ish gray colouring overlayed. This is brilliant for 2 reasons: 1. To separate the timelines from one another ensuring viewers don't get confused, and 2. It represents the two characters' situations. Ae ri is the one with the ability to change things for the better, thus the warmer tones (hope). Seo jin is in a constant state of stress, hence the colder tones (grief).

    I won't go into further specifics of my love for it, as that would delve into spoilers.

    I strongly suggest you don't look up spoilers for this show, as there's a lot of crazy plot twists that deserve to be seen first hand.

  • Your Honor

    3. Your Honor

    Korean Drama - 2024, 10 episodes

    8.5

    Simple but effective in many ways.

    Plot progression is fantastic. You essentially learn things in tandem with Song Pan Ho.

    Acting legends SHJ & Kim Myung Min compliment two actors that I believe to be some of the only good new talent in Korea today, Kim Do Hoon and Heo Nam Jun, very well. Park Se Hyun is brilliant as well. Together they elevate the story to something really special and insightful.

    Do you see and expect good and kindness from your child no matter their actions, or do you give in to the realization of a likely evil turn in character? Are they remorseful of supposed mistakes, or have they been completing further steps in a long con? Do you suspect, or forgive?

  • The Call

    4. The Call

    Korean Movie - 2020

    10

    A familiar concept to me, seen and enjoyed previously in both The Phone (2015) and in Kairos, and The Call joins them in harmony by executing the same idea in a unique way.

    Horror is my favourite genre and I think this is one of the best if not the best Korean specific horror movies I've seen.

    Jeon Jong Seo is phenomenal, Park Shin Hye does great as well.

    From story to acting, cinematography and direction, as well as practical effects and makeup, a complete knockout!

  • The 8 Show

    5. The 8 Show

    Korean Drama - 2024, 8 episodes

    8.5

    Excellent cast, excellent story.

    It felt like if Squid Game was an indie type production. The look and feel to it, almost echoed Wes Anderson at times.

    Park Jeong Min was a severe stand out. I hope he gets more substantial roles in television in the future. He seems to gravitate more to film.

    Chun Woo Hee & Park Hae Joon were great as always.

  • Doubt

    6. Doubt

    Korean Drama - 2024, 10 episodes

    8.5

    I am a sucker for father daughter relationships like this, especially when inserted into a mystery thriller.

    It's a wild ride with a completely satisfying ending.

    Chae Won Bin is phenomenal.

  • Nine Puzzles

    7. Nine Puzzles

    Korean Drama - 2025, 11 episodes

    8.5

    Excellent lead dynamic, which solidified the show as special no matter the result of the investigation.

    Built for multi seasons if you ask me. Could easily be grouped in with legendary mainstream pairings like Castle, Bones, The Mentalist, etc., if only they were given the chance.

  • 365: Repeat the Year

    8. 365: Repeat the Year

    Korean Drama - 2020, 24 episodes

    9.0

    Incredibly fast paced, full of plot twists, excellent ensemble cast.

  • Justice

    9. Justice

    Korean Drama - 2019, 32 episodes

    8.5

    I watched this as it aired and felt I was in the minority when it came to reception.

    I was genuinely hooked and on the edge of my seat from start to finish.

    Nana, Choi Jin Hyuk, and Park Sung Hoon are absolutely fantastic in these roles.

    The character dynamics and plot progression were so intriguing and easy to latch on to.

    No complaints.

  • Voice of a Murderer

    10. Voice of a Murderer

    Korean Movie - 2007

    8.0

    Brilliant and tense thriller.

    We're told at the beginning of the film that it is a true story, but it never really hit me until the very end. A punch to the gut.

    Kang Dong Won as the faceless kidnapper does so much with essentially a voice only role.

  • Train

    11. Train

    Korean Drama - 2020, 12 episodes

    8.0

    Your usual Korean detective investigation show, elevated both by setting- alternate reality/multiverse- and by a heavy heartstrong character- in the form of two Han Seo Gyungs, and their effects on our primary Seo Do Won.

  • Forgotten

    12. Forgotten

    Korean Movie - 2017

    9.0

    Starts as a typical spooky movie, only to play out in the most unexpected way possible. A mid-film plot twist that boosts it into pure excellence.

    Incredible writing, incredible acting. Bravo!

  • Missing Noir M

    13. Missing Noir M

    Korean Drama - 2015, 10 episodes

    8.0

    Great cases and good characters.

  • The Phone

    14. The Phone

    Korean Movie - 2015

    8.0

    Similar concept to Kairos and The Call, it does great with it's own plot and is a solid thriller overall.

  • Family Matters

    15. Family Matters

    Korean Drama - 2024, 6 episodes

    8.5
  • The Quiet Family

    16. The Quiet Family

  • D.P. Season 2

    17. D.P. Season 2

    Korean Drama - 2023, 6 episodes

    9.0

    Resonated with me more than season 1 did for some reason.

    Bae Nara's storyline was a definite stand out.

  • Stranger

    18. Stranger

    Korean Drama - 2017, 16 episodes

    8.0

    Incredible cast and excellent chemistry across the board.

    Good but standard investigation plot.

  • The Lies Within

    19. The Lies Within

    Korean Drama - 2019, 16 episodes

    8.0

    Episodes 10-16 of this show made it become one of my all time favourites. There's a lot of plot twists and story developments that happen which you wouldn't expect.

    However episodes 1-9 are quite slow and even slightly below average if I'm being honest.

    If you can manage to push through the first half of this show you will be rewarded with a sudden pace pick up later on.

  • Tunnel

    20. Tunnel

    Korean Movie - 2016

    9.0

    Incredibly tense thriller.

    Fantastic cast.

  • Train to Busan

  • The Host

    22. The Host

    Korean Movie - 2006

    My favourite Bong Joon Ho film.

    Horror movies with a family as their beating heart will always play well.

  • The Guest

    23. The Guest

    Korean Drama - 2018, 16 episodes

    Slow at times, but is true and proper horror which I appreciate.

  • The Ghost Detective

    24. The Ghost Detective

    Korean Drama - 2018, 32 episodes

    Had room for improvement but still enjoyable overall.

    Great chemistry between the leads.

  • Life on Mars

    25. Life on Mars

    Korean Drama - 2018, 16 episodes

    8.0

    It's a story that will have you wanting answers at the beginning, but by the end you'd prefer to have no answers at all. You'd rather have him stay with the people he's grown close to during his time in the past, instead of return to the bleak and dark future.

    Lee Do Hyun and Go Youn Jung's chemistry should be capitalized.

  • Broken

    38. Broken

    Korean Movie - 2014

    8.0

    A devastating movie.

    Under different circumstances you'd find the main character cruel because he's going after teenagers, but instead you actually end up rooting for him. The teens are portrayed as monsters and it makes you pity the main lead so much. I really just wanted to give him a hug.

    One scene in particular is one of the most heartbreaking things I've seen in film frankly.

    – When he's in the teen's place and hides while they replay the video...

    Pretty darn fun minus the iffy CGI!

    Jeon So Nee and Koo Kyo Hwan have incredible chemistry.

    Would love to see further seasons.

  • Weak Hero Class 1

    41. Weak Hero Class 1

    Korean Drama - 2022, 8 episodes

    9.0

    I am rarely able to get into school set shows in recent years. This one pulled me out of that rut.

    I've adored Hong Kyung for a while, but his performance as Beom Seok truly catapults him into the best Korea's young acting scene has to offer.

    The tone shift partway through the season is excellent and is really what sets the show apart from the usual teen dramas.

  • The Worst of Evil

    42. The Worst of Evil

    Korean Drama - 2023, 12 episodes

    8.0

    Pretty decent mob set thriller.

    Great and intriguing "villains."

    Our so called good guys are a little too high and mighty for my taste. They both had great potential to swing to the dark, even if not permanent, with genuine decision and feelings it could have easily made it go from good to amazing.

  • Moving

    43. Moving

    Korean Drama - 2023, 20 episodes

    Incredibly fun and grounded. Marvel and DC wish they could make a superhero work this great today.

    Mix of classic stars and up and comers who compliment eachother well.

  • Money Flower

  • The School Nurse Files

    46. The School Nurse Files

  • Extracurricular

    47. Extracurricular

    Focuses on terrible people coming to rely on one another.

    Very interesting dark topics at play, would have been nice to see further seasons.

  • The Guardians

    48. The Guardians

    Korean Drama - 2017, 32 episodes

    7.5

    Messy at times but easily saved by it's character work and relationships.

  • Cruel City

    49. Cruel City

    Korean Drama - 2013, 20 episodes

    7.5

    A decent plot elevated by it's characters and dynamics.

    Nam Gyu Ri's character in particular was the true standout. Her relationship with Shi Hyun and her sister-like bond with Jin Sook were the heart of the show.

    I also liked the setting (the mob world). While it's become more common nowadays with many of the Disney+ shows, it wasn't too common around the time that I watched this. It brought an overall darker theme to the show which helped bring a certain weight to everything going on.

    However I really hated the character of Ji Hyung Min and eventually ended up skipping through most of the police related scenes due to it. The constant switch back to the police investigation lost me quite often, which is a big drag when it's centered around a main character.

  • Nobody Knows

    50. Nobody Knows

    Korean Drama - 2020, 16 episodes

    7.0

    A lot of great young talent showcased here. The students and their relationships were what stood out.

    Unfortunately the cops and teachers weren't nearly as intriguing. On paper there's good backstory and motivation for both Young Jin and Sun Woo, but whether it be underwhelming performances or missing weight/depth to them, I never clicked with them. The supporting cops as well were more annoying than anything.

    As for the villains, I have mixed feelings. A lot of intrigue and potential there. Baek Sang Ho and his hotel crew would have been a little more enjoyable if they fleshed out their group dynamic and connections more. There's a moment near end where he and Sun Ah(?) seem much closer than shown to us prior. It was just a fleeting glimpse into what their relationship might be. I would rather have been shown a closer look into how he truly feels about his partners all throughout. It would have grounded him more. As for the original killer, the Pastor, super bland and uninteresting. It was good that they got rid of that point to the case so early on.

    Despite a somewhat hollow undertone, I was able to keep going and still be curious as to how it would all play out. The structure of reveals was well done, as they staggered all throughout.

    It's a good disposable mystery to pass the time.

  • Children of Nobody

    The cases at hand and their link were really interesting. All these different murders taking place, all resulting in a newfound life and better circumstance for a child left behind.

    Might have been a little bit better with different lead actors.

    I had a hard time caring about Lee Yi Kyung or Kim Sun Ah. Their performances invoked nothing from me. If there was more weight to their reactions and actions, I definitely would have at least liked them.

    The supporting cast on the other hand really shined. Cha Hak Yeon & Nam Gyu Ri filled their roles perfectly.
