It's no definitive masterpiece but it's damn close.

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.

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
