"Bitch Slap" earns its title. A post-feminist exploitation flick in which three gorgeous, big-breasted women beat the crap out of men -- and then one another -- this tongue-in-cheek parody sends up any number of films, most notably those by Russ Meyer ("Faster Pussycat, Kill, Kill") and Roger Corman, for whom the film's director/co-writer, Rick Jacobson, once worked. He also helmed many episodes of "Xena: Warrior Princess," so let's just say Jacobson is sticking close to his roots.
