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.

An old-fashioned movie made with new-fashioned finesse.

.Like the great film, it's made with a great deal of visible affection both in front of and behind the camera.
