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.

I have absolutely never seen anything like this movie before. You have to see this movie.

Worth seeing just to witness how winsome it is.

The movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.
