Girlfriends, on UPN, could have been another empty yuppie comedy, a black woman's Sex in the City. Instead, the sitcom about four female black professionals in L.A. is witty, smart and original, and it plays with race and class without relying on dry stereotypes. Luckily, the show will survive the impending programming cuts from the WB-UPN merger. If you haven't seen it, watch it.
