Nothing is as it seems in this bizarre, Hitchcockian mystery thriller. Unfortunately, it doesn't all add up, either. Don't wait for an ending that wraps it all up--there isn't any, which it too bad for a film that is very well made and acted. The story starts with a bang, a brutal and senseless assault that occurs before the opening credits. And then it builds ... slowly ... ever so slowly--at a pace some may find atmospheric but others will consider tedious. As the story finally progresses, it gradually reveals that what seems to be going on isn't what's really going on, as each layer of the story hits yet another twist, leading to yet another layer. Who or what is this story about? Who's the protagonist? Who's the antagonist? It keeps the audience off balance. Somewhere in the middle was the mother of all continuity errors, where a character was wearing a bloody shirt inside the house, then a clean version of the same shirt outside the house, then the bloody version again when he went back into the house. Was the outside an extra scene that was shot later and then inserted into the film? Or was this inconsistency purposely part of the story to convey that what obviously is happening isn't really happening after all? Several things that character does never add up and are never explained. For a horror movie, there's little gore, most violence is implied or portrayed indirectly, and the blood is downright artistic. The focus is on the story. The film is very well made, it's just too bad that the story doesn't make more sense.
