Can this be classified as hands down one of the most appalling endings in the history of famous manga?
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)
