Its been 10 years since Buffy Summers first walked into the Sunnydale High library and came face-to-face with her Watcher, who told her she was the Chosen One who would save the world from vampires. In the seven seasons that Buffy the Vampire Slayer was on TV, we watched her kill her true love (but he got better), graduate high school (by blowing it up), discover she had a sister (who… uh… was always there?), sacrifice her own life (but she got better), watch her sidekicks become heroes (and villains).
