Excellent, Without a doubt!!

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

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

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.
