Good films always raise compelling questions, whether the format is fiction or documentary fact.

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.

The film's masterful storytelling did its job. The message was clear. No need to overdo.

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