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.

Pretty good movie overall. First half was nothing special but it got better as it went along.

Clever, believable, and super fun to watch. It totally has replay value.

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.
