Good movie, but best of all time? Hardly . . .

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.

It's a movie as timely as it is provocative and amazingly, for much of its running time, it is weirdly funny.

The joyful confection is coated in a sparkly gloss, bright enough to gleam from the darkest, most cynical corners.
