Todd Graff’s Camp (B) is a joyous ode to growing up, making friends and finding your voice. Set at a summer camp for kids who want to be Broadway stars, there is enough backstage drama to fill the great white wilderness as the teens overcome their outcast status and find themselves center stage in their own follies, foibles and friendships. Graff draws out charming performances from newcomers Daniel Letterle, Robin de Jesus and Anna Kendrick, the latter belting out a very memorable and angry “Ladies Who Lunch.” The title’s play on words might imply a film high on kitsch, but it’s actually high on sweetness and coming of age. Showtune fans will rejoice at some unexpected songs and a star cameo. It’s Meatballs for maestros.
