The best films of this genre always show a path and provide a takeaway for being a better person.

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.

It's simply great fun, a winsome film and an occasionally over-the-top luxury fantasy that never flags.
