If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

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.

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.

This is ultimately a movie about the very bad things that can happen when we don't address our unease, when we just try to brush it off, whether that's to fit in or to preserve our self-image.
