Game of Thrones has been a goosebumps show until the final season. Season 8 butchered the show. It killed its storyline. If they don't know how to make an original and sensible story, they should have waited for George R. R. Martin to finish his 2 books.
Reasons, why season 8 killed the show, are:
The assassination of main characters and mainstreaming side characters. Ex- Daenerys is killed by Jon. Jon joined wildlings.
Daenerys - she has been the main protagonist of the show. She was the life of the show. In fact, her scenes were the most thrilling ones. If she was to be killed, then why do the writers hail her as the just ruler (breaker of chains etc.). The burning down of the king's landing seems like a made-up excuse for assassinating her. They had to kill her somehow to tie the loose ends and end the show. Great!
Jon snow - useless identity as Aegon Targaryen. He told Sansa and Arya despite Daenerys warning him. If he never had any desire for the throne, why did he reveal it in the first place?
The writers wanted to make twists, they wanted to keep up with the previous seasons, so they are trying really hard to come up with anything unexpected even if it doesn't fit the plot.
Jon killed the queen but went scot-free. He was sentenced to join night's Watch. He deserted the night's watch and joined wildlings. What a breathtaking ending. If someone killed queen/king, he can join night's watch and no one will care. So anyone can kill Bran the Broken and join night's watch. As simple as that. Very good precedent!
Tyrion - I was very neutral towards this character until he persuaded Jon to kill Daenerys.
In his one speech about "stories", Bran becomes the king. One speech leads to the abolition of all existing systems of inheritance & governance. One speech leads to the emergence of democracy. Are you kidding me? Don't insult the intelligence of viewers. There has been no sign of any such institutional change which usually takes centuries to build. Utter absurdity! And the "rubber lords" concurred with 'aye'.
Beware of Tyrion. At the first sight of a better ruler according to his intelligent mind, he will backstab the king.
Bran the Broken - what has he done? Nothing. He fell down from a fort and became the three-eyed raven. Everyone else burdened him on their shoulder. Look at the history, makers of the show. Nobody rules anything without ambition for power. That is human history. He will not rule the 6 kingdoms for long. That's for sure.
Secession - are you kidding? Sansa doesn't want to bend the knee to the iron throne. She wants the north to be independent. But she wants the lords in the north to bend before her. What a hypocrite. If the north can secede with just one statement, how do you think the integrity of Westeros will be maintained? Before long all other kingdoms will demand independence and Bran will become the king of just the king's landing and a "Broken Westeros". Bran cannot hold the Westeros together. No doubt!
Lord Varys - one of the most unstable characters. He can't be relied on. Executing him was the right option before Daenerys.
Small council - the inclusion of Bronn shows the quality of administration. How did Samwell Tarly become a grandmaster at such short notice? And what about his Night's Watch. Remember, desertion is punishable by death. We are not fools to believe such stupidity.
Daenerys was never given the chance to rule. She was being judged adversely even before her rule and treasonously and shamelessly killed by Jon. Jon should have committed suicide after this. Shame on you, Jon.
