Rewatched the final episode last night. Wasn't going to but it was on so gave it a shot. The first half of the episode was really good. Once the scene with Jon killing Dany and Drogon torching the Iron Throne and leaving with Dany's body was over the show fell off a cliff. It's almost like it was two different shows and the people who did the second half were Jr. High film students. Starting with the scene in the pits everything just got laughably ridiculous and made no sense.
My biggest issue with the show was the treatment of Jon Snow. I'm fine with where his character ended up, I'm not fine with how he got there. So while they are having this stupid meeting, at least Tyrion told Grey Worm twice that they had no say in Jon Snow's fate and all GW could say is "shut up, you are our prisoner". Okay, all of Westeros nobles are there and nobody brings up the fact that Jon Snow is actually Targ/Stark and the rightful heir to the throne? He killed a woman who burned KL to the ground and was actually a usurper since he has a better claim to the throne? None of this comes up? They talk about letting the King (Bran) decide his fate, Jon is the King you morons! You don't think that when the Iron Islands and Dorne learn the entire story, that Jon is the true heir, bent the knee not knowing he was the true heir, and did so in order to defeat the NK, and then killed Dany for her destruction of KL and realizing she was unfit to rule as she planned on bringing more death and destruction to Westeros, you think that after learning all that they would still want him punished? No way. They would have lined up behind him. The entire story surrounding Jon's fate was just screwed up, and it didn't help that Jon just sat there and didn't assert his claim, though it would have been out of his character to do so.
A better conclusion at that meeting would have been for the Westerosi to tell Grey Worm that he is holding the rightful heir to the throne prisoner and that there will be war if he is not released. Once Jon is released and given the throne he abdicates it and HE comes up with solution of the nobles choosing a leader as that is what Dany wanted, to break the wheel and a new way of doing things. Jon then chooses to go north of the wall and live with the Freefolk so he is no longer a point of controversy and that he feels he doesn't deserve to rule after all that has happened. It should have been his choice to turn it down, and it would have been a nod to that other Targ earlier in the show who chose the Nights Watch over the throne.
IMO, they completely bungled Jon Snow's story, he was THE GUY, the focal point of the story and in the end he was idiot Grey Worm's prisoner and his family threw him under the bus, again.
