Literally everyone except Daenerys got a happy clean ending.
This episode and this season as a whole have been a complete and utter disaster. the decline of storytelling quality from the last seasons is shocking. The show is barely recognizable at this point.
A character who wasn't a contender for the throne ended up on it even though they have done absolutely nothing this whole season, had lots of potential to make for a very interesting role but was ignored and swept aside then suddenly elected king.
Daenerys's character being completely butchered as she was turned from someone who never showed the slightest disregard to innocents' safety to someone who commits mass genocide and shows no remorse afterwards, all in the span of 2 episodes.
So many character arcs were neglected or wrapped up poorly. Jon being reduced to a secondary character with a combination of three sentences of dialogue, Jaime's development being thrown out the window, Cersei barely doing anything and then getting killed by bricks, Tyrion, the master tactician, turning to a gossiping idiot then getting promoted after he quits his job (seriously?)
So many plot points were discarded or turned out insignificant. Azor Ahai, Jon's lineage, The Lord of Light, Cersei's prophecy...etc
The whole White Walkers storyline being eliminated in one episode, then the whole Iron Throne storyline being eliminated as well in the end (FFS)
So much shit not making the slightest bit of sense. Dany's army multiplying, Arya's impenetrable plot armor, The North getting the independence while the Iron Islands didn't when they were the first ones to demand it, Drogon not killing Jon after he killed Daenerys, hell, the Dothraki and the Unsullied not killing Jon after he killed Daenerys, The point of the Night's Watch now that the WW are gone. Tyrion being in chains and holding up a presidential vote over who would run the 6 republics. HBO c'mon man.
Overall the pacing was too fast and inconsistent, the ending was rushed, anti-climactic and nonsensical. This couldn't have ended in a worse way. Kudos to D&D!
