“Night Teeth” (*1/2 out of four) was a toothless vampire melodrama about a college student (Jorge Lendeborg, Jr.) who moonlights as a chauffeur and picks up two women (Debbie Ryan and Lucy Fry) and subsequently finds out they are bloodsuckers and gradually gets sucked into their shadowy and violent world of vampirism and blood lust. By the standards of most vampire movies, this one is pretty anemic and could have used a transfusion of some style and conviction. Bizarrely, Megan Fox has a brief (and meaningless) cameo as a member of the vampire clan.
