I think she's the one we'll have to watch the most. I think Tyrion and perhaps Little-Finger understand, that she will eventually be the best at playing the "Game..." especially with her tutelage under Little-Finger. She is also the only one in a position that can revive House Stark which I hope really happens. This is just my prediction, I could be wrong, but I think she is going to end up murdering Little-Finger and will essentially become Little-Finger, the prime mover behind the events in Westeros.
Sansa is shallow, weak and stupid. That said, she is a survivor.
So many of the Starks are stupid, though oh so brave and "honourable". They pretty much get as they deserve.
The not stupid starks? Arya who's pretty much insane, Bran and young Rickon, though the wee lad isn't really around enough to detrmine if he's a smartlittle guy or not. So, benefit of the doubt to him.
But Poppa Eddie, Cat and Rob... DUMMIES! I dislike stupid with the burning intensity of the sun. But Sansa - she's just too bloody pathetic to hate, or love.
Of them all, only Cat could I hate as she's a woman wiling to destroy the seven kingdoms and lives of countless folk for herself (she says for her daughters, but I don't buy that). Cat is the character I most despise in the show/books ( a very close second is Gregor Clegane. But I gotta admit, she is a fascinating character study and very well portrayed by actress Michelle Fairly.
Anyway, I couldn't vote because neither statement is true, for me. I thank you for letting me rant!
