It has its moments, yes. I think part of the attraction is the simplicity of the whole thing, and of Buffy herself - the innocence, I guess you might say (the white dress is a fairly big clue there). It's fun to see her turn into a rebellious (well, somewhat rebellious) teenager and then an adult, too, but the innocence of early Buffy has something. Not just Buffy, for that matter.

I liked the episode with the nightmares becoming real more than Prophecy Girl, though. Perhaps because of Buffy's vampire face, first and last time we get to see that.

Well, yeah, but people need some visible reminders that "vampire" is more than just a word. Especially in Angel's case - we need more than just his word and vamp-face to know that him having a relationship with Buffy really would be complicated. And in that particular scene, the idea is clearly, for all that the vampire is a superhero, he's still not of her kind, and that she needs humans around her too. And of course he can't give her the kiss of life because he's dead himself.
