^I said "episode", not "show".
I'm not sure if it's fair to say that that was the point of "Chosen," either. But even if it was -- what, exactly, is wrong with doing one episode about the defeat of misogyny in seven seasons' worth of a feminist program?
It was the last episode. The last episode of any show worth a damn, which Buffy certainly was, is too important for such ham-fisted messages.
There's a whole other thread to be written about the way Joss and his writers write their most important male characters - wusses or monsters, most of the time. Wesley and Spike even managed to switch between the two, in opposite directions.
I am currently waiting for it to turn out that Langton beats up his girlfriend or something, he's been written far too much like the true good guy in this show so far.
