As my adrenalin continues to be revved up after the completion of this movie, all I can say is, I cannot conscious recommend this to ANYONE!! Why? The beginning of the movie that features the conflict between the two male leads is so hard to watch, so raw with anguish and disgusting behavior, no sane person would say watch this. Again, I am always awed and amazed at the depiction of bullying in Korean schools. It is unimaginable to think that anyone who is a victim survives with their sanity. And that is the crux of the story. Yang Dong Geun as Chang Sik was superb, as usual. Joo Sang Wook as the tortured and never to have recovered Joon Seok was utterly amazing! The story is SUPER raw and an emotional roller coaster. Not too often you can watch a movie and say "Kill them ALL". So can I say this movie was good? Not good, AMAZINGLY GOOD. Can I recommend? Unless you have the stomach to watch severe levels of abuse, rape, beatings, and few other things, you might want to skip this; however, if you can handle those subject matters, this is an well-acted and amazing story whereby the ending is exactly as you expected.
