Excellent, Without a doubt!!

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 isn't all that great, actually. Really cheesy and very predicable of how certain scenes are gonna turn play out. However, I guess that's the charm of it all, because I would consider this one of my guilty pleasures.

The film's masterful storytelling did its job. The message was clear. No need to overdo.
