5 Underrated Korean Thrillers Beyond Parasite and Oldboy
If you have seen Parasite and Oldboy, you already know that Korean thrillers play by their own rules: sharper plots, darker humour, and a habit of changing genre halfway through. These five get mentioned much less often, and they are all worth your evening.
1. The Chaser (2008)
Na Hong-jin's first feature follows a former detective turned pimp who realises that one of his missing girls has been taken by a serial killer, and that he has a few hours to find her. Kim Yoon-seok and Ha Jung-woo carry the film, and the chase barely lets up.
Why it's underrated: it is often overshadowed by the director's later films and by the bigger names in the genre, but the pacing is among the best in any thriller.
Watch it if you want a film that never lets go.
2. Mother (2009)
Before Parasite, Bong Joon-ho made this story of a widowed mother, played by Kim Hye-ja, who sets out to prove her son did not commit a murder. It is part mystery, part character study, and it takes some unexpected turns.
Why it's underrated: it was released between his two bigger international hits and is sometimes treated as a footnote. Kim Hye-ja's performance is one of the best in his filmography.
Watch it if you liked Parasite and want to see what else its director can do.
3. Memoir of a Murderer (2017)
A former serial killer with Alzheimer's disease believes his daughter's new boyfriend is a killer too, and he cannot trust his own memory. Won Shin-yun directed, with Sul Kyung-gu in the lead.
Why it's underrated: the premise is fantastic and it is often skipped in favour of better-known titles. It plays with the unreliable narrator in a way that keeps you guessing.
Watch it if you like thrillers that mess with your sense of what is real.
4. Forgotten (2017)
A young man moves into a new house with his family and begins to suspect that something is wrong with his brother and with his own mind. Jang Hang-jun directed, and Kang Ha-neul and Kim Mu-yeol play the brothers.
Why it's underrated: it quietly built a reputation as one of the better psychological thrillers of its year, and many people who saw it say they wish they had gone in knowing nothing.
Watch it if you want a twist that is worth the wait.
5. A Bittersweet Life (2005)
Kim Jee-woon's stylish gangster film stars Lee Byung-hun as an enforcer whose one act of mercy puts everything he has built at risk. It is more melancholy and more beautiful than most crime films.
Why it's underrated: it came out before Korean films were widely exported and still has a cult following rather than a mainstream one. The action is superb.
Watch it if you like your crime stories with real style.
