Not guilty at all, but dance competition movies. It’s a subgenre of sports team movies where a diverse group has to learn to work together to win a competition, but the competition is dance. Movies like Stomp the Yard, Bring It On, and the Step Up series. You may be inclined to think Dirty Dancing as well, but that one is too individual and with too much drama, though it does include the all-important training montage.
