This movie has sex scenes and violent scenes, so if you are a sensible person this movie is not for you but if you are not a sensible person and you like this kind of movie than you will love this one. What I liked so much about this movie was the fact that Soo-Hyun gave up everything to revenge his fiancé and to make the killer suffer as much as he could. While you watch the movie you will notice how Kyung-chul's eyes can make you turn on the lights again once you see how he doesn't feel anything after killing a person. The cast is very well chosen, achou Min Shik did a very good job as a psychopath, like I said before, just by looking at his eyes I wanted to turn off the screen because it's really scary, that only shows how good his act was.
