I liked Ygritte, poor Jon, at least he didin't have to choose between her and the Nights Watch since the decision was decided for him after her death.
Female Characters I dislike: Cersei, Lysa, Queen of Thorns, Margeray and Asha.
Those I Like: Brienne for all she is female she is also the one true knight in the books so far, besides some of those who have already died.
Meera, frogs aren't all that bad, and if the Frey's dislike them so much the Crannogmen must be good.
Arianne, she was just following her heart, although I admit she is rather sneaky, if only her father had taught her how to trust by trusting her she wouldn't have turned out this way though.
Arya because she is queen of the world in my eyes, she goes where she wants and does what she wants.
Sansa, the poor girl has been through so much and brutallized by one she once admired, these experiences have made her retreat so far into herself is it any wonder she does what she's told? Her beauty making every man want to rape her hasn't helped much either. Once she breaks free of her shell though she will be one to reckon with, even in ASOS her potebtial is beginning to surface, soon she will surpass Littlefinger at manipulation of people and keeping secrets.
Dany because she is the mother of dragons, need I say more?
Lady Frey (Her first name alludes me at the moment), the one that is Jaime's aunt and wife to Emmon who Cersei granted Riverrun to, although a minor character I find her open bluntness rather refreshing. She is a hypocrite and doesn't care to show it, she knows what she wants and lets others know as well, atleast that was how she was around Jaime.
I know I am forgetting some but that's it for now.
