This is one of those movies that suffers from sitting on the fence between two genres, and not fully satisfying either. Really, it is a thriller with slight supernatural overtones, which are never totally explored in any depth. The acting is good throughout, although I did find the leads constant state of helplessness a little wearying. In my personal opinion, I think it would have worked better as a straight out psychological thriller, as the supernatural side didn't really add anything to the story.
