I would be lying if I said I was not creeped out just a little. The film does hold you. No BOO fright clichés. Just that long sickening feeling that something crazy is gonna reveal itself. In the end does it? I dunno, maybe I would have preferred the alternate ending, I dunno. Cillian was great playing this part, there was something very Tim Roth about his eeriness. Obviously the film does recall Psycho. I like the clashing calmness dressed as Emma against the main character's nerves and fears. At the beginning of the film I thought the dude was an autistic adult. The train in the back yard, I believe its a metaphor, was awesome.
