Brett Morgen's Crossfire Hurricane and Cobain: Montage of Heck bent the rules of the rock documentary, but his David Bowie film, Moonage Daydream, smashes them to pieces.

If there’s a message at all in Moonage Daydream, it is secondary to the experiential nature of the movie. That’s hardly a knock. One goes to a concert to be thrilled, not necessarily to gather life lessons.

...a thoughtful, meditative, almost trance-inducing rumination on the meaning of art and life.

In this, we have the most endearing – and in its own way revolutionary – aspect of Bowie: he came in from the side, passed through the centre and went off again, by choice, to the outer edges.
