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.

Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

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 is definitely an excellent idea hidden in the background of the film. Unfortunately, it's difficult to find it.
