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.

It's a mild crowd pleaser for people who are exhausted by blockbusters.

All that we are seeing on the screen is happening with real people, real action sequences in the background, forcing the eye to watch as if we were there.

Amazing worth wacthing. So good. Biased but well made with many good points.
