I love Anya, Willow, Wesley, Darla, Jenny Calendar, Xander, Tara, Fred, Lorne, Joyce (she's grown on me), Lindsey, Doyle, etc.
I hate Buffy (ignorant, entitled, self righteous, arrogant, stupid, racist... hey she's like that guy on my way to uni each day who screams about the apocalypse, something about refugees, dunno, I try not to listen), Cordelia (an apathetic bully), Spike in S7 (really, for someone who yaps on about his glory murder days, the 'demon' within, he really is pathetic with all the puppy dog eyes and suck up tactics). I like him, however, when he is sarcastic, punk rock, sadist, insane self, like in School Hard, Lie To Me and Halloween. He was fun and liked the Sex Pistols and drank whiskey. What's not to like?
