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.

A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

The joyful confection is coated in a sparkly gloss, bright enough to gleam from the darkest, most cynical corners.

The movie really just wants to entertain people.
