Alright, I keep seeing this and I kinda don't want to trace back for redrawn stories. What the hell happened with the murata manga redraws? Why are people so upset? I stopped reading it just as the monster association arc was starting and now everyone's hating it, did they really change all the garou development stuff and after that? (If you could give me a tldr of the changes it would be greatly appreciated)
Murata redrawing some sequences isn't a new thing, something as far back as the Sea King conclusion was redrawn, but that's it, just a double page that didn't impact the schedule.
However, as the years went by Murata has really taken his redrawing habits to a new height, the Phoenixman vs. Child Emperor was redrawn in its entirety three times, which did start to impact the release schedule.
People at large didn't seem to mind those all that much though, as far as I can perceive it was the further divide between the webcomic fans and manga fans caused by the manga diverging more from the webcomic narrative that got people to look at whatever Murata does with a harsher filter.
The entire narrative of Saitama vs. Garou turned out to be very different in the manga version, Garou ends up in a very different place compared to the webcomic; that got some people mad, but it seems it is the whole handling of the Ninja Village Arc that really got even some manga fans a bit peeved, as not only the narrative is very different from the manga version but Murata broke his own redrawing string record, an entire year worth of chapter releases just got restarted due a redraw.
