It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

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.

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

Great movie. Not sure what people expected but I found it highly entertaining.
