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.

The film makes a home in your brain and the only cure is to see it again.

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.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
