Mmmm... I'll say half-and-half. People *do* tend to be pretty obsessed with sex, but not necessarily all that much - but you're also an anomaly if you think it's really out of whack.

I don't think that JKR is actually capable of creating that much character depth.

No arguments here. I can't say how much I'm sick of potentially important characters being nothing but cardboard cutouts - even core characters! (Ah, well, this is why God invented fanfic, I suppose, though what one does when one doesn't like that, I don't know.)
