Her character was interesting. We started out hating her but I've noticed how she has gradually become less shallow. It was really funny in season 3 when buffy was reading minds. Cordellia's thoughts had zero depth. What ever she thought was what she said. I read that they made fun of her character in Angel too.
I liked the way she stood up to the other mean girls in dating Xandor. The whole Xandor Willow thing was very stupid. Willow was cute and no male, especially one who thinks about sex all the time, is going to completely miss out on that about Willow until that moment he saw her in the black dress. Then he was all over her. Very stupid. They should have hooked up early and the lesbo thing should never have happened.
Oz found out he was a werewolf. :) I hope I'm not spoiling these episodes...I'm just filling in some info for ya.

Cordy's character can be summed up in one line she said to Giles, after he accused her of being tactless. "Tact is just not saying true stuff. I'll pass." :)
