Stephanie Zacharek on Buffy's will-to-power: "'Buffy the Vampire Slayer' has always been a show that takes chances, but it seems to be headed in a direction that's more daring than ever. In a culture where sex is supposedly all around us and yet true, intense sexuality is in desperately short supply, the show's openness -- its willingness to face up to the messiness and potential danger of sex -- is glorious and revelatory."
