"Chosen" (Season 7, Ep. 22)
"So here's the part where you make a choice."
"Chosen," the series finale, is truly epic: a noble sacrifice, a beloved character death, the most badass Wicca spell ever, and, of course, the final battle of the Slayers versus the Über-vamps, which rivals scenes from Lord of the Rings.
But what makes it great is what makes the whole show great: its feminism. Buffy's feminism is imperfect, it trips and it staggers, but in "Chosen," it lands with a single message: "I say, my power should be our power. From now on every girl in the world who might be a Slayer, will be a Slayer. Every girl who could have the power, will have the power. Can stand up, will stand up. Slayers, every one of us. Make your choice. Are you ready to be strong?"
