The movie runs out of plot and jokes well before the end of a two-hour running time, long for a light comedy.

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

The film never slows down or bores, plunging from one harrowing sequence to the next.

The movie is wonderful and true, an act of love in all its contradictions and complexity
