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.

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

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.

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