The cast is excellent, with Ji Chang-wook and Wi Ha Joon delivering standout performances. Ji Chang-wook is particularly impressive in his portrayal of Jun-mu, a complex and conflicted character. Wi Ha Joon is also excellent as Gi-chul, a young man who is forced to grow up quickly in a dangerous world.

The production values are also high, and the drama creates a dark and atmospheric world that is both believable and terrifying. The action sequences are well-choreographed, and the special effects are convincing.

Overall, The Worst of Evil is a must-watch for fans of crime thrillers. It is a dark and disturbing drama, but it is also a well-made and suspenseful one. If you are looking for a drama that will keep you on the edge of your seat, then The Worst of Evil is definitely worth checking out.

However, I would like to caution viewers that this drama contains graphic scenes of violence and torture. It is also not suitable for children.
