Sean Fine and Andrea Nix Fine’s celebratory and dazzlingly scenic documentary is Bring It On, Uganda style — which means the rough-and-tumble northern dance troupe fighting for the national title comprises kids from a refugee camp, some whose parents have been murdered, some who were abducted into rebel armies as mere babes. It’s Africa lite, but the movie lets us think of these kids as talented, funny, self-aware characters, rather than victims. And their dynamo tribal-dance numbers are flooring.
