This could have been a provocative film about sportsmanship, independence, and fraternal love. Instead The Sixth Man wavers between sopped-tissue drama and crotch-grabbing locker-room antics as Kenny Tyler (Wayans) learns to stand up for himself when his older brother Antoine (Kadeem Hardison), a self-serving superstar, dies. Reincarnated as a mischievous ghost, Antoine creates havoc while leading the team to the national finals. Wayans and Hardison give solid performances, but the computer-generated physical humor can’t match The Mask, and if you’ve seen a single sports film, the plotting will be as familiar as Michael Jordan canning a game-winning shot in crunch time.
