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 great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

One of the most extraordinary films you will see this year. Take that as you want.
