Step Up Revolution

(PG-13) ★★★☆☆

This entertaining kids-gotta-dance musical taps into the dance “flash mob” phenomenon. The story is an overfamiliar one, but the dance scenes—with the mobs dancing on the roofs, hoods and trunks of low-rider vintage cars in Miami traffic, disrupting museum openings and a developer’s planning meetings—are a brilliantly choreographed, well-shot and sharply edited treat.
