For those of you who wish "So You Think You Can Dance?" had a plot, there's this acrobatic flick. The story concerns a ragtag group of hip-hop dancers determined to win a prestigious b-boying competition that Americans have lost out on for the last 15 years. It's kinda, sorta a fictionalized remake of director Benson Lee's 2007 documentary Planet B-Boy. Josh Peck (from Nickelodeon's "Drake & Josh") stars. Chris Brown is in it, too. 109 minutes PG-13.
