Tired before it begins, REBOUND never figures out how to handle Martin Lawrence's vibrant spacticity. As arrogant, bling-obsessive college basketball coach Roy McCormick, Lawrence is contained by clichés. The movie is most bearable if you consider the adults subsidiary and focus on the kids, in particular Big Mac and Wes, who develop something of a romance once he tutors her in math and she starts punching out kids who tease them.
The plot, such as it is, is rendered mostly by montages of familiar pop music -- practices, pep talks, games, rides on the herky-jerky school bus that Roy and Newirth take turns driving, and headlines announcing the team's miraculous winning streak. By the time you're hearing House of Pain's "Jump Around" on the soundtrack, you know the formula has run its course, that Roy will make the right choice, and the championship game will end unsurprisingly.
