What Sarah brings to the part is her intelligence, at the same time, she's got that hormonal, idiosyncratic goofiness that makes Buffy not just the Terminator.
What bothers most critics of my work is the goofiness. One reviewer said I need to make up my mind if want to be funny or serious. My response is that I will make up my mind when God does, because life is a commingling of the sacred and the profane, good and evil. To try and separate them is fallacy.
Do goofy stories make people nice? What if, in their goofiness, these stories somehow inspire that in the right way. Is that a social good?
