I'll defend Bleach's ending. The ending was rushed and Tite Kubo didn't exactly get to tell the story he wanted to tell. The light novel CFYOW was left to tie together a lot of loose ends. When you take that into account, you CAN see the story Kubo was ultimately trying to tell and there were enough pieces in TYBW alluding to events of CFYOW that do make me believe the stuff in the light novel wasn't completely pulled out of its ass. When you put all that on paper, you have a relatively decent story in theory. It's disassembled and you have to squint really hard to see it, but there is a good story there and the anime has made lots of good changes integrating parts of ideas from CFYOW.
AOT has no such defense. That ending was mostly planned out from the beginning. Hell, neither does Naruto. I am firm believer that the idea Kubo's health was the main reason Bleach was forced to end so quickly is a lie or a secondary reason at best. Kubo was claiming to have another decade of story left in him at the start of TYBW and I have a feeling that freaked out folks at who wanted the Big 3 era to end for whatever various reasons. Sure, his health probably was a factor but not the main one. I also find it very suspect we didn't get an explanation on the rushed ending until around the time the TYBW anime was announced.
