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.

Simple and well acted, it has tension enough to knot the stomach.

It really made me laugh, but for some moments I was tearing up because I could relate so much.

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.
