Buffy the Vampire Slayer: The Origin by Christopher Golden

This is the canonical version of the film. It's not a great comic, but it gives Buffy's backstory before the series starts. I'd recommend reading it after watching at least the first episode of the TV show.

"The origin comic, though I have issues with it, CAN pretty much be accepted as canonical. They did a cool job of combining the movie script (the SCRIPT) with the series, that was nice, and using the series Merrick." - Joss Whedon
