Eh, there were a lot of decisions that essentially made it impossible to write a good story for the ending. Just off the top of my head:
Arya using her Faceless Men training once. She could have probably just paid to kill Walder Frey…
Zero payoff to the big Targaryan reveal - other than it pissing off Dany
Why Arya decided to go travelling.
Bran barely used his abilities. Man could’ve warged into several beasts and fought during the main battle, and outside of being a moody bitch he doesn’t really do anything other than act as bait.
Who was the legendary lord of light? Was it Jon? It kinda seemed like it, but it makes a lot more sense for Arya to be the one.
Thematically, it would have made a lot more sense for Jaime to reject Cersei, and for this to be the catalyst for her to go crazy - with Dany going crazy from achieving slow victory that chipped away at her claim.
Varys was too clever for his story to end like it did. IMO he should have been able to escape his capture, and fled away from Westeros.
Unpopular opinion: The show runners did the best job they could, because with the limited time they had there wasn’t really an option for a better ending. They really needed at least another two seasons, but the reason GRRM hasn’t written another book is because he knows he’s written himself into a corner - and rather than try to fix it through TV and give himself an “out” he criticised the ending he probably had a hand in creating, and won’t ever finish the story.
