Garbage writing to wrap it up. The show was interesting in part because of the character development and dialog. They removed that from the last few episodes. Varys became flat, Jon became a waffle, Cersei was put on the bench, Grey Worm was castrated completely, and Brienne was made to blubber about Jamie. Tyrion lost his wit and became the great explainer. Daenerys was never a very strong character to begin with, which was probably the weakest aspect of the whole series, and yet, her transformation was too quick to be believable. It was boring that Bran should be voted king, and hilarious that Sansa said no thanks and no one got to change their vote, however, it wasn't what actually happened that was the problem. The problem is that they betrayed the work that had been done and just got sloppy. The dragons were so wild that they could barely be controlled by Daenerys, but then one became philosophical upon her death, and destroyed a metaphor. Sam presented the history of the war to Tyrion, and for the purposes of a joke, informed him that he wasn't in it, which would be impossible, seeing as Tyrion killed his father, the guy that sat in the Iron Throne. Not worth the shitty joke. Arya rode out of the ruins on a pale horse with a look of vengeance, then to walk out without purpose. Grey Worm teleported. The whole modern beverage easter egg thing was probably a symptom of shit going downhill. The show did interesting things like the red wedding, Ned Stark's death, Cersei's shame walk, the fire bombing of the temple, and Hodor. The death of the night king and the ruin of King's Landing could have matched up if the writing wasn't shit.
As a writer, I find that when people don't like the way things happen they say that the "writing is bad." If they can give examples of what would have made the writing better, they have a legitimate beef. Seasons 1-6 allowed the characters choice. It gave them options to explore, consequences to endure and a number of paths to follow. Seasons 7-8 have been about the culmination of those choices. Varys, whose career has been about undermining the Baratheons, is suddenly faced with the fact that there's a better choice than the one he's backing. He has no choice. Jon, who has always put others before himself, has to put others before himself. He has no choice. Cersei, who has always put her own needs before others, ends up with no choice. Grey Worm finally does something for himself - he chooses vengeance over chain of command. Brienne became a knight, got the guy, had the guy leave her, and stayed a knight. Not only that, she bloody manned up and forgave the guy when it came time to write his fate in the book. Tyrion realized that all his wit painted the world into a corner and did what his heart wanted - very much like when he executed his girlfriend and father. The great explainer? he got Jon to murder the rightful queen of Westeros for the good of the people. Daenerys has always been a strong character, it's just that her strongest actions have always been betrayal and vengeance. She reached maximum betrayal and vengeance, and experienced maximum betrayal. It is boring that Bran should be king. The argument of the series is that "boring" is better for the smallfolk. The first people we see the series? Bystanders murdered by an ancient grudge and misapplied justice. Who makes out largely okay in Game of Thrones? Hot Pie. Gendry. The Onion Knight. It's an extremely proletariat story wrapped in the trappings of feudalism. Sansa gets to keep the North because nobody wants to go to war with the North. They're really the only army left standing. Arya beheld a pale horse. She looked death in the eye and said "not today." She put her purpose down. The girl with the murder list not only didn't follow The Hound into Hades, she got her fill of killing. Which was the whole point of burning King's Landing - everyone got their fill of killing. Except the Unsullied, who have had humanity driven out of them since they were little boys.
