Who exactly is bordering on feminism and why?
Her masterplan to take the Dreadford doesn't exactly add her profile of a strong female character and would be a ludicrous attempt to "feminize" the storyline.
Makes Robb Stark "Lets take Casterly Rock! With the Boltons & Freys!"-move appear witty.
I'm unsure about the long-term prospect; On the one hand they have taken strong alterations and will have to make stronger ones to keep the show interesting.
On the other hand, the TV programme is full of shows that have outlived their creative spark and are carried on due to their never-ending support by the audience (Dexter, How I met your Mother & Simpsons as worst examples)..
As GRRM is on board, its safe to say they will be more or less sure how the books will end, if they get an end at all.
