A breezy, often bizarre animated feature straight from the id of writer-director Sylvain Chomet. The story follows a morose little boy who becomes a world-class bicyclist under the rigorous training of his grandmother, but that’s just a basic premise. Chomet’s sensibility, brought to life through a rough drawing style resembling lovely scribbles, combines an eye for the ugly side of human nature with an underlying affection for his pitiable creations.
