Time to lick that heroine addiction, folks. Not only is Buffy the Vampire Slayer star Sarah Michelle Gellar expected to hang up her wooden stakes at the end of this season, but, since the WB has grounded Birds of Prey, tonight's episode (airing at 9 ET) very well may be the comic-book drama's last. But don't chalk up the disheartening turn of events as a victory for small-screen big bads. What cooked Birds' goose was more likely the been here, done this vibe that viewers got from watching Ashley Scott — as Helena Kyle, aka the Huntress — go through the motions that once made Buffy our Chosen One. Consider the facts. — Ben Katner
