I've already gushed about how cool this WB show - an artful mix of My So-Called Life, Heathers and Dracula - can be, so I'll try to keep it short. But what else can you say about Buffy The Vampire Slayer, a program that dares make a hero of a cheer-leader-turned-super-strong-ghoul-killer who vacillates between going to her high school prom and killing the most evil vampire who ever lived? Buoyed by a fresh - faced cast that artfully manages teenage sarcasm without being tiresome (Janeane Garofalo, are you listening?). Buffy is so good, it's a shame the show has been consigned to the low - rated depths of WB. But if she can rid the world of vampires, it should be a snap to find a higher-profile home.
