In this delectable and vivacious debut feature, shy 14-year-old Benoît (Réphaël Ghrenassia) moves to Paris and a new high school, where he’s rejected by his cooler classmates and reluctantly sidelined into a precarious friendship with the “freaks and geeks.” The New Kid is a rare case among coming-of-age movies: a portrait of allegiances made and broken among middle-schoolers that calls special attention to the uglier, less picturesque aspects of passing through puberty. The movie’s rhythm never stalls and its tone stays charmingly light partly thanks to its wonderful cast—a skilled and magnetic group of first-time young actors.
