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.

Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

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 most extraordinary films you will see this year. Take that as you want.
