The Worst Evil offers up a gritty take on organised crime, South Korean style. First off, this is a "violent" series. Lots of bloody, downright vicious battles, between Korean gangs. This aspect may be a bit much for some viewers. If you can move past the brutality, there's a lot to like here. An engaging if familiar story, populated by an interesting array of believable characters. Thus far I'm into only episode one and I'm already hooked. In summary, yet another addictively watchable, gritty, crime drama from South Korea.
