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.

In truth, there is barely enough story here to make a film.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

It is encouraging that the film ends so strongly.Otherwise, it wouldn't have been a particularly memorable film
