Scary and disturbing as hell, the kind of movie that makes Panic room look like a movie for your little sister! One of the best "huis-clos" I have ever seen, don't miss it! Too radical to be a Hollywood movie, the kind of movie everyone should show to those kids who still think that the sixth sense (not the wonderful Michael Mann version of the Thomas Harris world, no, I'm talking about the director of the probably overestimated Signs and of the highly underrated Unbreakable) is frightening! And I'm not talking about monsters or ghosts, I'm talking about human beings...probably the scariest monsters of all time!
