Very very predictable, including the post credit scene !!!

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 wanted to like it more than I actually did... But much of the humor totally escaped me and I walked out only mildly impressed.

Let me be very fair here, this is not the best movie in my opinion. But, this movie is fun, it has purpose and is very enjoyable to watch.
