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.

It's a mild crowd pleaser for people who are exhausted by blockbusters.

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

By the time the dramatic fireworks start popping off, each one feels earned.
