I think ASOIAF has a lot of good, feminist appeal. I think GRRM set out to use and subvert some of fantasy's archetypes among which the female characters stereotyps and was very successful with some but not quite so with others (I'm not very happy with the way he deals with Cersei, for one).

The number of people who hate Sansa is incredible and very annoying to me. Like the people who blame her for Ned's death, rather than, you know, hating Littlefinger, Joffrey, Cersei and Ned himself (Sansa was no smarter than Ned but she was certainly not worse, and Ned's also to blame for having a nice talk with his favourite daughter Arya and seemingly forgetting to have it with Sansa). The thing with Tyrion is totally ridiculous, especially given that Sansa rather recognizes the fact that Tyrion is kind to her (and tells him so!). Tyrion's issues with women and self-esteem issues overall are definitly not Sansa's fault nor her responsability to deal with!

The whole thing comes from the point of view that women only matters for how they relate to men, men's desires, men's angst, etc. blargh.
