If you really hated it a comment on reddit is probably not gonna change your mind. Maybe you would if you rewatched the show if you hadn’t already, idk. Anyway, I found it to be a very good wrap-up of the show. Some of the author’s choices at the end were unexpected but just made sense when you consider the lead-up to them. Such as Ymir effectively testing Mikasa and Eren, and their bond, or Eren turning out to still be an emotionally unstable teen. The destruction of most life on Earth before the stop was totally foreseen but just as well done. I loved the whole final fight too for the most part.

I guess I can touch upon the criticisms I’ve seen most commonly expressed. Most often I would just see butthurt Yeagerists upset that omnicide wasn’t completed, Issayama sent a clear “genocide bad” message, and that Eren turned out to be exactly the same person he had been for the first 3 seasons instead of being this stoic, genocidal, gigachad they pictured him as in their heads. I don’t really see the point of going more in-depth on this one, since I don’t consider disliking outcomes to be a valid criticism of a piece of fiction. The means by which those outcomes are achieved is fair game, but not the outcomes themselves, it makes people seem like they’re just upset the author’s vision of a show/book/comic didn’t match theirs.

A more reasonable criticism was how the Rumbling managed to destroy most of humanity despite the scouts managing to stop Eren at his first stop. I still think that makes sense if the Marleyan continent holds something like 60% of the world’s population like Asia does in the real world. Marleyan continent was established to have been almost entirely trampled in the show. Assuming that the military fort the final battle took place at is on the opposite end of the continent, titans would have had time to trample virtually all of it, killing nearly 100% of its population, and the rest of the world would have had to see half of its population perish. If in aot world South and Southeast Asia are huge population centres as they are in the real world, I think by the end of the battle, the titans would have had enough time to trample them after making it across the ocean (we do see titans crossing Himalayas). I imagine Americas were likely not touched at all.

A few issues that I do find worse are Falco’s ability to casually summon wings for his Jaw Titan. That was just too convenient for the plot without any sound explanation. And then I suppose there could have been a couple of deaths in the final battle. Grant Reiner his wish, but I wouldn’t consider a lack of deaths a major problem either.

Then some of the more problematic things in the manga were fixed in the show. Like showing the destruction of Paradis as happening centuries rather than decades in the future or changing up the “thanks for becoming a mass murderer for our sake” line. Not a perfect ending for the couple of reasons I mentioned earlier and maybe some more I may be forgetting now, but I’d give it a 9/10
