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.

While it doesn't offer any answers, it both thrills and makes you think.

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.

One of the best movies of the year! Incredible from the beginning to the end.
