¡Viva la Revolución! No. Not really. Step Up Revolution, the fourth film in the series that launched the career of Magic Mike himself, Channing Tatum, is kind of the dance-floor version of those Resident Evil movies: So little actually changes from chapter to chapter, and you can't believe the franchise is still going, much less making money. This time around, a bunch of anonymous, good-looking dancers work it for the chance to win $100,000 if they reach 1 million hits on YouTube. (Really, all they'd need is a singing cat, but whatever.) It even borrows a hook from Breakin' 2: Electric Boogaloo, the original movie that used dancing to stop money-grubbing land- developers. You might expect the acting and the dialogue to be awful, and you have no idea how right you are, but that's why these are movies about dancing and not acting and dialogue.
