Toe, I'm with you on Kennedy. Hate her. She's a spoiled, brash brat, and nowhere near good enough for Willow. And her pre-sex speech came out of nowhere for her character. It was exactly the thing Will needed to hear, and would have drawn tears had Tara said it. But nothing Kennedy has ever done or said leads me to believe that she has that kind of sensitivity or perception, let alone level of emotional giving.
I know they probably won't kill another Willow lover, but I really wouldn't care if she bit it.
