The greatest movie ever!

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 film never slows down or bores, plunging from one harrowing sequence to the next.

I enjoyed watching this film and would recommend other to give it a try , (as I am) but this movie, although enjoyable to watch due to the better than average acting fails to add anything new to its storyline that is all too familiar to these types of movies.
