I mean, lots and lots of characters didn't die. The endings for some were satisfying, but for most they weren't. And the fact that all these endings happened in the context of a completely nonsensical heel turn by one character just killed any semblance of satisfaction there may have been. And of course one character had incredible plot armour for the entire series and clearly had a huge destiny attached to him. Does he save the world? Does he become the rightful king? Does he die heroically trying to do those things? Nah, he just f***s his aunt and then gets a half-assed ending as a punishment for doing the right thing.
Notice how the show just completely disappeared from public discourse? The last two seasons were so badly done, and the ending was so awful, that everyone just wants to pretend the show didn't exist. That they didn't invest so much time in watching the show, and re-watching while waiting eons for the next season, and all the mental energy thinking all week about what is gonna happen next, what so-and-so is planning, what that guy meant when he said that thing.... it was all to get to that ridiculous end.
You know what? f*** that shit. that show doesn't belong on my list.
