I gave this film a 9 out of 10, because it was exactly what I expected it to be.

Clever and entertaining enough to recommend even to members of the 1%

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

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.
