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.

After playing with our expectations, this turns out to be a very different sort of film.

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.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
