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 was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

If you like to be scared, if you like to laugh, and if you like to learn a thing or two at the movies, this absolutely cannot be missed.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
