Good start, but then it gets ruined

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.

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

The movie is made so realistic it has a lot of that WoW feeling at the right moments and never tooo over the top. the suspense is done so well and the emotion is felt. Very well put together with the music and all.
