Then explain to me why would they cut Bran, cut important characters like Arianne and Young Griff, have Sansa be raped (which really contradicts the theme of her character in the novel), turn Ellaria into a crazy bitch, have something as awful as tonight's episode (seriously, wtf...).

They would never have something like that occurs to their babies Tyrion and Dany.

^Yep. I really liked Tyrion and Dany from the beginning, but they've come to seem pretty Mary Sue-ish.
