I agree about it being fantastic (hoping you're not being facetious or sarcastic either). I find the neo pseudo writing experts who've apparently declared Game of Thrones "broken" sort of amusing, but I wish they'd just be honest: the 1 million or so who've signed the petition against season 8 really just didn't like where the story went. That's all.
Jaime going back to Cersei? They didn't like it. Daenerys becoming the villain? They didn't like it. These are not "broken" character arcs, they're just twists & decisions they didn't like.
As I wrote earlier, when Tyrion walked into the same inn as Catelyn Stark & she arrested him (thus starting the entire conflict between the north & the Lannisters), it was a major contrivance to get the war the writer wanted. But who cared? The ride was fun & people still had their fantasy. But when their favourite characters went in a direction they didn't like, kaboom, that fantasy was ruined for them personally.
It's sort of amusing how the two biggest entertainment products of the year so far (Avengers Endgame & Game of Thrones, i.e. both fantasy fiction) elicit such different critical reactions. Game of Thrones is subjected to the most nitpicking & over-analysis of its writing to an extent in which my eyes bleed (fans literally declaring it broke some "narrative rules" they plucked from thin air), whilst Avengers (with time travel as a plot convenience to defeat the big bad guy!) faces no such scrutiny. Why? Because people got their power fantasy for their favourite characters in Endgame whilst Game of Thrones stayed true to its themes (absolute power corrupts absolutely) & didn't deliver a Marvel ending.
Since Sunday we've faced a barrage of people screaming in our faces (I'll paraphrase) "it's shit, shit, shit & if you don't agree you don't know what good writing is". Well, I think it's freaking awesome & the Bells was one of the most visceral & intense moments in TV ever. Criticism is essentially a necessary part of entertainment of course (it basically can serve to make future products better) but the level of venom (freefolk reddit is a smouldering crater of hyperbole & outright insanity) directed at Game of Thrones is just "unnatural" & at odds with what we've actually seen on screen. The main criticism which could be taken seriously (i.e. there wasn't enough time dedicated to showing Daenerys fall into madness) can be rejected based upon the fact a normal movie is about 2 hours long & often features far more twists (Season 8 of GoT is over 7 hours long), whilst the suddenness of her unilateral decision was also the entire point (a tyrant with a WMD is capable of the worst, always).
