A spin-off of a sequel, Beauty Shop plays like most Hollywood comedies these days -- as tepid sitcom, benign product, and cynical afterthought. If Barbershop 2: Back in Business was little more than a dilapidated retread of the charmingly lightweight 2002 hit Barbershop, consider this incarnation condemned for teardown; it should have never opened its doors. It doesn't even try to be different, because it assumes the moviegoer wants only the same-ol' and then offers even less. Cube's Calvin has been replaced by Queen Latifah's Gina (the former's love interest in Barbershop 2), who, like Calvin, is up to her neck in pains in the neck. The writers, working with director Bille Woodruff, apparently felt they could justify their paychecks by taking the first two movies' screenplays, replacing men with women and women with men, and moving locales. As if.
