Two Detroit basketball whizzes (Anthony Mackie, Wesley Jonathan) pocket big bucks playing street ball in an underground league, but it’s a professional dead end that disqualifies them from college play and carries little potential for an NBA career. It’s a great topic, but this lethargic drama by Preston A. Whitmore II is a real air ball, so poorly scripted that most of the major plot developments occur offscreen. Sony is marketing this for the hoops, yet there are only two court sequences, at the beginning and the end; the rest of the movie has the heroes huffing at the shady dude who manages the league and mooning over a pair of slinky manicurists from the local mall.
