Such a frustrating disappointment

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.

There is, somehow, an interesting story here, as well as some good acting. There are also some good scenes

Let me be very fair here, this is not the best movie in my opinion. But, this movie is fun, it has purpose and is very enjoyable to watch.
