François Ozon arguably let audiences off a little easy with his last two films, the amiably light Potiche and the wryly witty yet discursive In The House. But the director, known for piercing deep into the nature of sexual mores, is back with a doozy in the form of Young & Beautiful. It’s part coming-of-age drama, part thigh-slapping family satire and part morality fable. Fans of the director craving another toothed, bracing effort will find themselves very much at home here. Isabelle (Marine Vacth) is a 17-year-old girl who has developed a natural curiosity about sex and soon enough endures an awkward encounter in which she loses her virgnity (when are they not?) to a local boy. Soon enough Isabelle decides, of her own volition, to become a prostitute. How this will affect both her clients and her family, she is oblivious to until her wild new life eventually — and some might say inevitably — comes suddenly crashing down.
