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.

The film makes a home in your brain and the only cure is to see it again.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

One of those movie experiences that is so good it makes you realize you've been grading everything else on a curve.
