I don't think they're criticizing the choices made about characters. One of them said they had taken Dany to the edge nigh on perfectly, and that they refused to show the push over that precipice.
This episode started with that final push.
Last episode had tyrion and varys discussing it. That was the precipice. But it had been brewing a long time. Varys thought she had lost it when she killed the tarleys. Tyrion didn't want to believe him. The evidence was all there. We saw her say some crazy things the last season and change.
This episode started with Varys telling anyone who would listen about jon. He may have been trying to poison her. He clearly was trying to undermine her.
Tyrion told her she'd been betrayed and she said by jon? No, varys. Yeah well, jon told sansa, sansa told you and you told varys.
And you could tell that he was scared of her as he explained that as hand he had to tell the master of whispers and maybe i made a mistake but but but...
And she said why did sansa tell you?
She knew her monarchy was over before it started. But she still had a dragon.
Then she literally told him her plan to burn down king's landing. And that wasn't some crazy unexpected thing. It was just that he wanted her to be better than that. A good queen.
And she responded that she was being merciful by making sure nobody would ever be ruled by a tyrant again ever.
She was breaking the wheel. Like she said she would 3 seasons ago.
Tyrion didn't like her plan and wanted to give the city a chance to surrender, but as she said to jon later in the episode, her claim was already irreparably weakened. She would have to rule by fear.
And she was fine until the bells.
Remember varys and tyrion talking about the bells? I've always hated the bells. They ring for horror. A dead king, a city under seige... A wedding?... Exactly.
The show told us this was coming. They showed the throne room burned down with ashes falling. Danny literally told us exactly what she was going to do. It wasn't until we saw it that we realized just how awful it was. It wasn't a bunch of soldiers and also some commoners. She went street by street through that huge city and burned it to the ground. And then we realized what it had meant to be cheering for the dragon queen to go home and conquer the seven kingdoms.
I love it.
