There are points when the director allows his voice to ring a little loudly from behind the camera, but the richness and depth of both the photography and the characterisation manage to brush any signs of preachiness and sentimentality from view.
A fine and perhaps unique example of that trickiest of genres, the road movie, and the sort of film that really does deserve the cliched response: they don't make them like that any more, because they really don't.
The fragmentary approach could never be called exhilarating, but it has a sly humour, and the mood is sustained by Vogler and Rottlander as the unlikely companions.
