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.

Simple and well acted, it has tension enough to knot the stomach.

I saw this movie before reading any reviews, and I thought it was very funny. I was very surprised to see the overwhelmingly negative reviews this film received from critics.

This is a must-see and one of the best documentaries - and films - of this year.
