I don't think there's any character who is universally loved. No matter who they are, there must be someone out there who hates them. Not that I hate Clem--I'm just cold about him. Although I did always wonder what happened to him after S6, and once had a fic idea where he met Spike in early S7, and Spike found out about Buffy bringing Dawn to Spike's cave after the attempted rape (I always wondered if Spike ever know about it).

As for who I love: The obvious: Buffy, Faith, Spike. I love Warren, too, but not in a very loving kind of way. I love most of the main characters, some more than others. More obscure characters: I developed a bizarre soft spot for Harmony, although she also annoys me a lot.
