From what I hear about the comics recently, they pretty much undermine everything Whedon did in the finale. I stopped reading them years ago because they just . . . weren't satisfying me at all in terms of story. And I hear it's only gotten worse.

I think the thing that bothered a lot of people in Buffy fandom about the finale was that it was not explicit that the girls got to choose whether they wanted the power or not. After the explicit rape metaphor earlier in the season, and after years of watching Buffy's life be - not ruined, but definitely complicated by the slaying, it seemed unfair that all these girls who didn't get to choose had those powers thrust upon them. My personal canon is that they did get to choose, on a metaphysical level; certain fic writers have done it that way, and that works best for me.
