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.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

The movie really just wants to entertain people.

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.
