It is not deep, but it is fun to watch. It does have a bit more of an edge to it than other similar films.

This is a must-see and one of the best documentaries - and films - of this year.

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

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.
