I have to ask then, what would be major then, in your estimation? I'm curious where your line is drawn.
I'm not sure, really. I'd have to see it to know it. But I think it would be something that was very concretely contradictory rather than just poorly presented. To use the Scorpion example....I can believe that the Iron Fleet could hit a flying dragon who was not expecting their attack, and I can believe that Dany and Drogon could effectively attack and defeat the Iron Fleet despite their Scorpions. The conditions are different in the two events, so I don't see them as contradictory. I don't think the first was portrayed very well, but I don't think that a matter of presentation is the kind of thing I'm talking about.
To use another example....I would have gone (and expected them to go) in a very different route with regard to Jaime. I think in the books, it's very likely that Jaime will help the Hound defeat the Mountain (pretty sure Dany has a vision of this in the House of the Undying; something about "a golden knight and a hound fighting a giant knight with armor made of stone", paraphrasing, but that's the gist) and then he'll go on to actually kill Cersei (fulfilling the prophecy of the little brother). He'll be faced with a similar choice as to the one he faced with the Mad King, and he'll make the same choice, because he knows it's right. That's the arc I wanted for him, and the one I think he's on in the books (if Stoneheart can somehow let go of her hate, I suppose.....maybe someday we'll find out).
However, the show went a different route. Jaime remains faithful to Cersei despite the influence of Brienne. He simply cannot move past the horrible things he's done, and so he thinks he belongs with Cersei rather than a worthy person like Brienne. Then he has his chat with Tyrion, and he essentially sets out to try and save Cersei in order to redeem her. I think he genuinely wanted to simply escape with her and live their life with the baby quietly for the rest of their days. Obviously, it wasn't to be so.
This is a different route than I would have taken, but I don't think it's at all inconsistent with what we've seen in the show. Book Jaime has a much more definitive falling out with Cersei that Show Jaime never has. I don't have a problem with the show's interpretation of this simply because it doesn't match my expectations.
EDIT: Furthermore I think at this point (season 8) some of us have been more than a little charitable, especially given the last few seasons. It isn't just one episode or one season that has been a clustercluck so forgive me if I don't share the lets poo-poo on the fanboys for their attitudes.
For me it is about common sense and consistency (in character and other). That has been sorely lacking for a while. The chorus is getting louder these days.
That's fine. You are absolutely entitled to your opinion. I expect I even share some of your opinions about the show. But may I ask, if the show has let you down so much, why do you still watch?
I try to temper my expectations with the realities of production of a show on this scale, and with trying to complete the story in the amount of episodes that remain. I'd have preferred a few more episodes so that things don't feel so rushed, but that was not to be. We can guess as to why, but likely our guesses will fall far short of the complexity that goes into a film production of this scope. "Just make more episodes" is a pretty easy thing to demand, and quite another to actually produce.
I do think that there's a strange phenomenon that happens with fans sometimes where they create expectations that will simply never be reached. And then very often what happens is that valid criticism ("the pacing of later seasons seems a bit too fast") is replaced by insult ("Dumb & Dumber have brought this on themselves"). You can see it in this thread, and you can see much more of it elsewhere online.
