Seems like everybody's rushing to make a third film in every half-bit Hollywood series just so they've got an excuse to stick "3D" in the title. Here, for example, is the not-so-hotly anticipated follow-up to Step Up 2: The Streets. Of course, it's got no connection to the previous films—other than the fact that it's about some streetwise hip-hop dancers teaming up with a classically trained college dancer to, you know, shake up the dance establishment. Ignore the weak acting and the predictable story, though, and you'll be treated to some incredible, acrobatic dance moves. In 3D, no less.107 minutes PG-13.
