Collider has compiled a list of underrated Korean dramas that have slipped from the spotlight amid the constant stream of new K-drama releases, arguing they deserve rediscovery by audiences now that the genre has a much larger global following. The piece highlights shows that predate or sit outside the recent K-drama boom, noting they often lack the international recognition of newer, higher-profile titles despite strong writing and performances.

The list includes Prison Playbook (2017), a comedy-drama from the creator of Reply 1988 starring Park Hae-soo (later of Squid Game fame) and Jung Kyung-ho as a jailed baseball star and his childhood friend; and Through the Darkness, a serial-killer drama likened to Netflix's Mindhunter, based on the memoirs of South Korea's first criminal profiler and starring Kim Nam-gil. A third title, Navillera, is introduced before the supplied text cuts off, alongside two further entries not detailed in the excerpt provided.
