I don't understand the dislike for Sansa. IMHO she is one of the strongest and most pitiable characters in the entire storyline. A noble daughter raised in a strong house suddenly having her world swept from beneath her feet. She finds herself fatherless, unprotected, held captive to a cruel and bitter boy/king and the machinations of his evil mother.
I root for Sansa and want to see her come out on top.
It don't matter what line we hand you
When we come a crawlin' in.
We ain't wrong, we ain't sorry,
An' it's probably gonna happen again.
