Perhaps the title of this feature-length shoe commercial should have been "Mike’s Nikes." Teenage rapper Lil Bow Wow stars as orphan Calvin Cambridge, a basketball Cinderella who joins the LA Knights as a promotional gimmick and ends up schooling teammate Tracey Reynolds (Morris Chestnut) and the best of the NBA superstars on and off the court — all thanks to a magical old pair of Michael Jordan’s sneakers (close-up on the Swoosh). Commercials can be very entertaining, of course, and John Schultz’s film is a feel-good comedy with several big laughs and considerable energy throughout, even when you know who’s going to sink the winning shot. It rides on the bright-eyed charisma of Lil Bow Wow and the playful representation of every youngster’s basketball fantasy: to dunk over David Robinson, pickpocket Allen Iverson, and stay in fancy hotels with room service. And the story hardly seems farfetched when you consider that high-schoolers are annual first-round picks in the NBA draft. Parents might even enjoy the subtle critique of the league’s greed and its players’ lifestyles (probably unintentional since the film’s execs head NBA Entertainment), though they’re not likely to cheer the way the reckless behavior of the 54-inch star is glorified.
