K-dramas have always cycled through themes, if supernatural romance is popular then suddenly there are three more lined up in production, if noona-dongsaeng relationships are de rigueur then every network will have one in prep, and so forth. This year in 2021 K-ent is calling it the year of the anti-hero viligante, the baddie taking down even bigger and worse baddies on behalf of the innocent average citizens. Starting with Vincenzo, then came Taxi Driver (Deluxe Taxi) and now we have The Devil Judge (Demon Judge), it’s the same playbook with different elements is all. To be honest, Mouse also fits the bill but having the male lead be an actual serial killer was one step too far, even if it was beyond his control and also there equally bad if not worse villains around him. The feeling is that viewers feel catharsis when they see bad people punished even if it’s by another bad person, because so often a good person doesn’t have the ability to commit bad deeds for the greater good. I think this genre is hitting at the right time when people more than ever feel a sense of helplessness in life, but if it’s done too often the thrill will dissipate.
