舞出我人生4

It's amazing that the dancers in "Step Up Revolution" can move so well through all that cheese.

The fourth "Step Up" movie has arrived, and of course it's full of invigorating dance numbers that are made all the more entertaining by the 3D technology. Alas, the dancers have to stop sometimes to allow the utterly unoriginal story to be told, and the romance at the center of it inspired Amanda Brody, the screenwriter, to produce dialogue so cheesy as to be laughable.

After dancing its way across Baltimore and New York City in previous iterations, "Step Up" moves to Miami. A streetwise guy named Sean (Ryan Guzman) meets a privileged gal named Emily (Kathryn McCormick), and a romance is kindled. So is a lazy plot, the old evil-developer one: Emily's father (Peter Gallagher) wants to replace Sean's Miami neighborhood with a giant commercial development.

But no one goes to a "Step Up" movie for the plot or the romance. Only the dancing matters here. Sean and his pals have a flash-mob dance thing going, and Emily persuades them to use the attention their guerrilla performances receive to mobilize opposition to the development.

"Revolution's" mix of choreography, contrasting modern dance and street-style performance that incorporates hip-hop, step, acrobatic moves and Cirque du Soleil-style aerial stunts, forms an energetic, constantly shifting mosaic. Several major set pieces, including the opening downtown Miami sequence centering around a parade of low-riders, help anchor significant plot developments, even if they add little narrative impetus.

By now, however, 3D dance performances are routine for the genre and with the exception of a few notable aerial tricks, "Revolution" doesn't offer many stylistic innovations, although the soundtrack featuring performances by Far East Movement (with an assist from Justin Bieber), M.I.A., M83, Diplo, Timbaland and J-Lo, is appropriately propulsive.
