One of the worst movies I've ever seen

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.

I cannot think of one single thing that I would change about this film. The acting is incomparable, the directing deft, and the writing poignantly brilliant.

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