Some people think that this is either Benioff's and Weiss's or even GRRM's commentary that strong women are always crazy women. I don't think that argument is worth discussing. FWIW, GRRM describes himself as a feminist. GRRM created many characters of different genders and sexualities, all of whom are varying mixes of good and evil, intelligence and stupidity, competence and ineptitude. It is almost certainly not a meta-commentary by GRRM or show creators on the danger of female leadership to have Daenerys burn down King's Landing. The fact that so many people joyously read Daenerys as avenging feminist Messiah is a testament to GRRM's creative abilities, nothing else.
The second, more numerous and to my mind more legitimate detractors are not necessarily THAT bothered by Daenerys going Mad Queen but think that it wasn't earned in the show. The show is all we can go on here as these events have not taken place in the books. On a private board I frequent, and on quora too I might add, this last episode caused heated discussion. As one show watcher pointed out on this blog:
This made no sense for her character as depicted in the show. Just last season she literally rebutted that she is "not here to be the queen of the ashes" when Yara and the Queen of the Sandsnakes urged her to burn King's Landing. That was 1 season ago. 1!!! Now all of a sudden she's the mad queen? Not buying it.We must remember that unless and until Benioff ,Weiss and GRRM give us a detailed look at what were GRRM's contributions and what were Benioff's and Weiss' we may never know what events were GRRM's "true" ideas. For all we know GRRM might be reviewing screen events and decide to alter or more deeply explain story events. Still, for something this big and character defining as the near total destruction of King's Landing my money is on it being GRRM's intent all along. So Daenerys was always going to go bad.
