This is a loosely defined list of Korean films generally showcasing mystery or police procedural elements. Most, though not all centre around serial killer cases but several veer into supernatural horror. Basically anything I've seen worth recommending that's South Korean and has a dark tone and an unravelling mystery at it's core.

These aren't all masterpieces on the level of Memories of Murder and The Wailing but they're all worth checking out in my opinion.
