At first rather annoying in its heavy emphasis on reenactments, this movie ultimately proves fascinating, simply because the complicated, highly dramatic tale it tells still almost defies belief.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.

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