I do believe there as more to Angelia hate of Buffy than what he had shown. That was why he wanted so badly to end the world. So, I liked this very much.

I like it) I think it could become long story AU Season 2, where Angelus would fight with his own nature because of his feelings for Buffy.
Anyway, Buffy/Angel is one of the most profound love stories, I think, the best of TV shows history. Perhaps another story, hm?
