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.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

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