Is it a challenge to make everything into some sort narrative on social norms? Half of these things aren't even true and the ones that are would be gender dependent. Cersei was going to die pregnant, Dany was snapping because she was a Targ and it's been talked about dozen's of times in the past, Arya just killed the ******* night king and they made a point to point out that Brienne was a virgin.
I liked the episode and I have to believe that this will be close to the narrative that the books would have taken. I just feel that the writing has been rushed to the detriment of the characters, especially the women characters. If we had the novels, I'm sure GRRM would have dug deep into the characters psyche on why they did what they did, but we don't have that. The Dany stuff I can buy, because right off the bat in this episode we hear she hasn't eaten in a few days and she looks run-down when she kills Varys. The voice-over of past Targaryen's going mad also helped sell the scene, but we've had so few of these moments that it seems out of place and more of a "cop-out" by the writers to help them say "yup, she crazy" rather than have hinted at that in previous seasons.
The Arya-Hound scene drove me nuts, because you could tell that Rory McCann and Maisie Williams were trying to sell something more than the Hound saying "you don't want to end up like me" and it just was not landing at all. You are right, Arya killed the Night King and it was awesome. Yet she is 100ft away from an unarmed and lightly guarded Cersei Lannister with the skills of an Assassin and training from various Knights and she just walks away. I feel like there is more to it that the books will sell better: such as Arya can change her face into anyone, yet the Hound proudly wears his scars as his identity and wouldn't change himself at all. Maybe that is what they were trying to do, but they didn't execute well.
