Things I liked:
- Dany's madness leading to a mass slaughter after she won, instead of just showing in a battle or a punishment, and then she gets knocked off for Jon. If you're going to make her mad, sell the heel turn big time. They did.
- Managing to make Cersei and Jaime semi sympathetic in the midst of it all.
- Cleganebowl - they gave the Hound his sign off from the show, and really just about the only appropriate way for it to end.
Things I did not like:
- As usual for the last couple years, pacing and set up are all off. Dany goes mad too quickly, hurting the plausibility, and also making Varys' betrayal seem more hollow. Not enough set up for either, nor for Jaime's decisions.
- Jaime vs Euron was a too convenient waste of time. And they also picked the wrong wounds for Jaime to suddenly recover from enough to win the fight and go find Cersei.
- On the opposite side of time and pacing, they spend a bit too long on Arya's traumatic escape. They have now spent more screen time making her hate Dany than they spent making Dany go mad. They needed to do something, but they oversold it. Arya and Sansa already don't like Dany.
- It relates a bit to the pacing, but they did a really poor job with the extent to which dragons are vulnerable and then not. Drogon won the battle single handed in 2 minutes of screen time. Which makes the survival of Euron's fleet the previous episode all the more galling and stupid.
- Oh look, Jon Snow is useless again. Does nothing in the battle vs the others, simply there to process horror in the sack of KL, with all the armies more or less irrelevant. The lord of light brought him back why? As a plot device for a battle for the throne, and to help drive Dany mad? Neat.
- Qyburn was a bit too cool a character to go out like that. So cool for so long, and he just becomes a plot device to pivot Cersei into vulnerability and despair.
- Does anyone really care who ends up on the iron throne now? The sense I've had all year of "just give some closure and end it" is even bigger now. Tough to actually root for anyone to win, it is just a race to the ending to be able to say the plot was resolved.
