The Dardenne brothers shoot chronologically in an unfussy style that rattles along with no music and naturalistic acting, often from first-timers. It fits this tale to a tee.

The central figure is Bruno, a teenage petty thief whose life consists of doing deals, getting by and avoiding employment. If there's money, it's quickly spent. His girlfriend has just given birth and he's slightly less interested in the baby than in his new jacket. He's not evil, he just has no conception of the consequences of his actions.

The film's title could refer to him as much as the unfortunate infant arriving in the world but the Dardennes never philosophise or judge. They just follow the restless Jérémie Renier, who knows the price of everything and the value of nothing, through an ever-changing set of circumstances.

At a time when so many films seem bloated and flabby, this speeds breathlessly through its 100 minutes. Filmed as is usual for the duo, in Seraing, an industrial town in Belgium, it won the brothers a second Palme d'Or at Cannes, after Rosetta.
