It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

Although I seem to have had higher expectations than I thought, the movie is super entertaining.

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.
