Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

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

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

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