Instead, the title of this fifth film in the series is as bland as the members of the competing dance crews that populate it. Perhaps there’s some allure here for true devotees in that characters from previous installments return and collaborate, “Fast-and-Furious”-style. (Sadly, Channing Tatum—who began his rise to superstardom in the original “Step Up” back in 2006—is nowhere to be found. Then again, he has far better things to do these days.) If you’re a newbie, you won’t be lost—this isn’t exactly a Christopher Nolan film in terms of narrative complexity—but you’ll probably be checking your watch as you wait for the next dance number to start.
