I was a Buffy fan, used to love when Angel went all bad too. But Spike and Drusila, I absolutely ADORED. Especially Drusila. My word, what a nutter.
Also, I really hated Harmony and Cordelia. I still hated them even in the Angel series.
Oh, and I loved Alex. I mean really really really loved him. I actually cried when he died. :'( First TV character I dote on that's NOT blonde and they kill him off. Was such a disappointment.
And I watched Angel, up until Cordelia got jiggy with Connor, whose diapers she had changed not even a few months before. I mean, that's just wrong. That was the last episode I ever watched and never touched either series again.
