In truth, there is barely enough story here to make a film.

it is finally so absorbing because it plays like a lyrical road odyssey that’s also a detective story.

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.

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