I think whole time fuckery being introduced was downfall to the story.
First,Eren infulencing whole lot of events really dont make sense if you look from pre timeskip point of view.
Griesha would have supported Eren in Genocide and now his dialogues with Kruger makes no sense. Did Eren infulence Kruger to send his pops to paradis ?
Isayama changed entire thing to show Eren was mastermind genius setting this up is bit of a stretch , he is no aizen for godsake. He could have done it simple way instead choose to show Eren was plotting stuff to make sure his friends get credit makes no sense.
Overall for the anime only fans will not likely suffer the fate like we did. The studio will likely twig the ending or extend few scenes to make it look better.
idk stuff like death note is up there and it was pretty fucking awful, but AOT's awfulness is the level of like quality directly BEFORE the ending.
to elaborate, DN declined right at the halfway-point (specifically, the introduction of near) and the ending was an absolute dumpster fire that was consistent with the writing downward spiral that had preceded it.
in contrast, attack on titan has been one of the best manga/stories in general to date, and the fact that the ending sucked so much fucking ass when everything leading up to it was pretty damn good might make it top the charts as the worst (or at least worse than DN)
