Plot so thin, it passes unnoticed.

I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

Go in cold, and you're likely to emerge with your blood boiling. This has to be seen to be believed.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
