I like movies that are aware of what they are selling... without [any] greater aspirations than to make people laugh and that's it.

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

The movie turns out to be a little better than the average. Starting from a romantic formula often seen in the cinema, it ends in the most predictable (and somewhat bland) way.

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