I Saw the Devil stars well-known Korean actor, Lee Byung-Hun and is directed by the amazing Kim Jee-Woon who has done nothing but great films so far. I Saw the Devil is the ultimate Korean revenge movie. When the daughter of a federal agent is killed by a serial killer, he goes on a mission to exact his revenge and becomes a monster himself in the process. Despite some gruesome scenes, this movie explores the mind of someone who will do anything to get even. Some great performances by Lee Byung-Hun and Choi Min-Sik, this movie will always be at the forefront of what I consider to be great Korean cinema.
