I've read a few posts about female characters in tv series recently. And they're mostly about whether it's ok to slag them off or not. And sometimes about whether they can be people we identify with in the way that the male characters are. I think the first is true if the second is, that is, it's ok to slag them off if at the time you think they're potentially good role models. So when fans make crass comments about River Song in Doctor who, about her physical attractiveness, calling her whiny and bossy, and wishing she was dead, it's not ok. Bitching about Buffy's perm at the beginning of season 4 is just fine. What was she thinking?
