According to GRRM, the main goal is the iron throne. He didn't want the final big battle to be against the walkers. The big fight is against Cercei. So I'm sure Jon and Daenerys still have the chance to become heroic saviours of the day.
What's so surprising or controversial about the fact that she did it? Even from the little I've seen I understood that this character was obviously supposed to be a game changer.
Taking over? These strong female characters have been there from the very beginning (I hated Melissandre or what's her name, she was so OTT).people are annoyed that "women are taking over the series" and that GoT has become "politically correct" etc.
Where did he say that? Game of Thrones is the HBO title. The book series is A Song of Ice and Fire
Well, the criticism is from more than some men who don't want a woman doing it. Many if not most of GoT readers and viewers have been gung-ho supporters of Daenerys for years, who,in case you missed it, happens to be a woman. As for Jon Snow, in the books, and even in the show, there have been signs and portents about Jon Snow being brought back to life for a reason; if that reason is simple political intrigue, it is as bad as the LOST frozen donkey wheel. I think Arya is a great choice for the surprise factor, but if they really had planned it for three years, they should have planned their whole show accordingly, not just that scene. If GRRM ever finishes his books, he will resolve whether it was the plan for Arya all along (and I am sure if it is he will have more things pointing to it than the show), or it was Benioff and Weiss stunt episode plotting in action.

Many of the male characters (from what I've seen) were weak, clueless or psychopaths. I think Jamie Lannister was the most interesting male character? Is he still alive?
