One piece is the only one that didn't feel like they were making shyt up as they went along (in terms of main plot), just the adventures themselves were long as shyt.Most popular long running shounen manga don't make it half as long as One Piece without a complete implode. Many of them end in disgrace like Naruto and Bleach for example. They were called the big three and the other two the fans had pitchforks out before they ended. MHA was supposed to inherit the crown and people shyt on it. Attack on Titan people trash the ending. The final saga of DBZ was even meh overall.
With bleach and Naruto you could tell they were just stringing shyt along. MHA would introduce so much pointless shyt, on top of making these kids unrealistically scale up to compete with adult killers.
Attack on Titan just put themselves in a corner where no matter what, there was gonna be a side that was angry with it jjk may end up the same way considering Gojo/Sukuna/Geto are so far ahead of everyone else, we gotta wait n see tho
I think Demon Slayer did a good job of getting straight to the point and finishing, I don't recall seeing an uproar, but the damn anime may end up stretching things out and ruining it for anime onlys
