I'm beginning to lose interest in Kay Scarpetta. She's so unremittingly unhappy all the time, and so is her supporting cast. And it only gets worse as she gets older.
I think it was in the BVS episode of Biography that Joss Whedon says he'd noticed, "Buffy happy, ratings down. Buffy unhappy, ratings up." This may explain my dissatisfaction with BVS, which is a different dissatisfaction than most fans had contemporarily (which I disagree with). When BVS wrapped up I wrote, "I don't have the same quarrel with the last two seasons that most of fandom does. But when I look back on them I have very little recollection that Buffy was in them."
