I never followed any GoT hype and finally started watching the show 2 months ago and just finished. Never read any discussion because fear of spoilers.
I'm curious how my rankings compare to others
... My rankings:
S1>S4>S3>S2>S5>S6>S7
Show clearly kind of lost it after S5... S6 was just terrible imo, outside of a few battles & scenes (Cersei destroying everyone was very cool, but my main emotion was intense relief that the horrible high sparrow-plotline was over). S7 was not terrible but I really don't like where they've taken the plot. I know the night king has always been a part of the show but it showing up at the end as "the ultimate badguy" and everyone uniting (or trying to) to battle him is turning it into a completely different show imo. It's like suddenly Game of Thrones turned in Harry Potter (I love both, I just mean that in HP the ultimate badguy was the focus since the beginning & it was clear where the plot was heading).
I think what also killed this show is that they always want to have a ton of characters, and they really failed in replacing the magic of everyone they killed off. This started becoming really apparant in S5 & on for me.
Finally, there's only a few kills where I thought "the show killed off this character too soon", but the worst one has to be Lord Baelish
. I understand that once that Bran is back in Winterfell they have to kill him off, but I was hoping he'd realize he was in danger and escape.
