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.

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

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
