>Why was the TV series ending so hated?
Loaded question, but to answer it you have to start with season 7, not season 8.
1. Euron's character was butchered. He was supposed to be a final boss style dark lord who wore magical armor, wielded a horn that could control dragons, and know a bunch of esoteric knowledge about the gods and the undead. The show ignored all of this and just made him an edgy pirate who just wanted to fuck Cersei. This ended up MASSIVELY biting the show writers in the ass, because when they got to the point where Euron had to kill a Dragon, they realized they the show version of Euron wasn't competent enough to kill a Dragon, so Daenerys and Jon had to go full retard and FORGET about his navy for Euron to score a win against him.
2. Cersei's insane plot armor and how it actively shits on the realism of the world. It's no secret that Westeros is a patriarchal and deeply religious society, which means it should've been impossible for Cersei to become sole Queen of the country. Because 1), Cersei is a woman and entire WAR was fought to prevent a woman from seizing the throne, and 2), Cersei BOMBED the setting's equivalent of the VATICAN, along with the POPE and the WEALTHIEST and most politically POWERFUL people in the country. It's utterly preposterous that Cersei was allowed to keep the throne after this. Had the story still been written by GRR Martin at this point, then Cersei's head would've been on a pike for her stupidity. Instead Cersei somehow becomes queen, and not only does she become queen, her subjects are LOYAL to her and willing to fight against DRAGONS for her.
3. Daenery's descent into madness was poorly done and rushed. Pretty self explanatory. Her heel turn from savior to insane mass murderer didn't really make any sense, and as a result it still gets memed on and mocked to this day.
4. Arya. From Season 6, it really feels like Arya doesn't even belong in the show. She can casually shrug off wounds that have killed stronger characters in the series (such as Drago), she can beat a master assassin with no formal training, she can fight a 6 foot tall knight clad in heavy armor and wielding a broadsword to a draw with only a rapier, she can assassinate an entire house of nobles and then bake them into a pie without the noble lord of the land finding out, and she can slip past thousands of undead warriors to launch a sneak attack on the Night King.
5. And while we're on the subject, Arya STOLE Jon's role in the story. It's VERY clear in the story that Jon is supposed to be the Prince Who Was Promised. He is the Song of Ice (Stark Blood) and Fire (Targaryen Blood), he is the secret prince who was raised to believe he was a bastard, he is the man who rose from nothing to Lord Commander of the Night Watch and King of the North through merit alone, and he is the man who came BACK from the dead because the gods weren't done with him yet. Killing the Night King and saving the realm from the Long Night was his whole reason for existing. But instead the writers gave it to Arya to subvert expectations. I'm not joking. They literally didn't let Jon do it because "it would be too obvious".
6. Jon was also lobotomized from a cunning and ambitious man who craved power, to an honorable fool who "doesn't want power"
7. The time scale is completely fucked. Gendry running from the North to Dragon Stone in a few days is the biggest example. In season 1, that journey would've taken months to happen. In Season 7, the journey happens in like 3 days. It's proof that the writers just don't give a shit anymore about making the world feel real.
8. Sansa. The writers try to portray her as a high IQ Machiavellian Schemer and a genius leader, but she just comes across as a retard. The show portrays her as cunning and ruthless for antagonizing Daenerys, but it's moronic; Daenerys is her ally and she has dragons, so acting like a bitch to her makes no sense. The show has Sansa walk up to a Blacksmith and I shit you not, tell him that he needs to put fur on the armor because winter is coming and people will be cold. The B L A C K S M I T H that's been making armor in the north for decades is being lectured by a teenager on how to make armor. Fucking lol. Oh, and her infighting with Arya proves she's a retard who can be easily manipulated (even though the writers want you to believe otherwise). She only realizes she's being played after Bran helps her, which is ironically further proof that she's a retard and that she's incompetent.
9. The Dornish pretty much disappearing from the plot, even though they have an army of 40k people untouched by the War of the Five Kings that devastated every other kingdom on the continent. Euron killing the Sand Snakes (like 5 people lol) is treated like the end of Dorne in the war.
10. Infinitely responding Dothraki. The Dothraki are literally wiped out in the Long Night. Like down to the last man. They lead suicide charge with glowing swords and we see them ride off into the distance to fight the undead, only for every single light to fade away in a few minutes. The writers even confirm this in a post episode interview, "This is the End of the Dothraki". But...they're literally ALL back in the next fight in King's Landing like nothing even happened.
11. Tyrion became a total retard. In previous seasons, he was a brilliant schemer and a capable commander. When he becomes Daenery's hand, he just makes fucking retarded decisions that no sane person would ever even suggest. Daenerys has 3 dragons, 100,000+ Reachmen, 40k dornish, a Greyjoy Fleet, 20k-40k Unsullied, 100k Dothraki and she loses to Cersei who has...30-40,000 Lannisters tops and a Greyjoy Fleet. It's clear that Tyrion only exists in the story at this point to stop Daenerys from instantly steamrolling through Cersei's army
12. Somehow the Seven Kingdoms are okay with the North seceding from the Seven Kingdoms AND Bran becoming King of the other six Kingdoms. And, they're all okay with this...even the Vale and Dornish who should still have the largest armies on the continent. Somehow the Starks get away with controlling TWO kingdoms while the other 6 Kingdoms have to eat shit and submit to them.
13. Bronn becoming Master of Coin and Lord Paramount of the Reach, even though he's not a noblemen, he can't read, and there are several other POWERFUL lords with an actual claim on the land. He would've been hung in a week, tops, and then someone like the Hightowers would've seized control. But that didn't happen. And it's proof that the show writers don't give a shit anymore. Bronn became Master of Coin simply because he's a fan favorite. It's literal fan service that has no place in the story.
14. The long and awkward sex scenes that served no narrative purpose. Arya fucking Gendry comes to mind. And so does Greyworm fucking Missandei. Why did we need a 5+ minute scene of a literal eunuch dry humping a woman? Why was this given screentime over something far more important, like...Jon and his family's reaction to his Targaryen heritage.
There's more, but these are some of the biggest issues
