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.

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

While it doesn't offer any answers, it both thrills and makes you think.

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.
