It's quite interesting to have a landlord psycho stalker with access to the house. It's a modern day Norman Bates thing and it was quite watchable during the initial moments of creepiness. But things didn't get any better and just ends in a predictable anti climax.

The unnecessary flashes of ER horror were cheap and detracted from the story.

Hilary Swank isn't suited to the suspense genre because her face is not expressive of fear. She's just got a bit of a horse like grimace going on. Jeffrey Dean Morgan (the Javier Bardem lookalike) isn't too scary.

The ending is weak and clichéd without any originality.

Overall not worth the time. Forget it.
