How much is the possibility of these problems getting fixed soon? or fixed at all?
The animation is unclear but I can't imagine it going back to what it was (i.e. filler arcs, nationwide standard broadcast, golden time slot)
The manga has been doing gangbusters since end of DR and I think fans will warm up over the course of the year if they handle the 20th celebrations appropriately and target the audiences they should be.
Also, do you think One Piece reception will remain stagnant?
Nope. I think Oda's call of 5 year reader turnaround is accurate. It would take a miracle to reach Strong World - Z- era sales again but that was a sales miracle. The magic cocktail of Paramount War and Strong World's Volume 0 might be possible to replicate in Wano and DEFINITELY in the final saga.
Maybe it's time to revert back to having 9 chapter volumes again? If the problem is a divide in the manga fandom, then maybe having the volumes release a little bit sooner could aid in keeping the volume-only readers closer to the discussion.
Yeah, there's not one given problem but rather many small ones that could be alleviated in this modern age to ensure that the fan community is as linked and sociable as possible. I would love to see a return to the '2 month, 2 month, 3 month' tank release schedule from days of yore but that's gone the same was as 21-22 page chapters.
Speaking of readers, are 5th and 6th graders not as engaged with Sanji's dilemma and the Big Mom pirates? Do they find Whole Cake Island not worth discussing as much as prior story arcs? Maybe the marriage politics and the food setting of WCI isn't resonating with younger readers?
Most youngsters are anime fans first, manga fans second. Super fans will read JUMP but I'm talking specifically about the average elementary-age fan. That is to say, most of them are still in Zou. Those few who know what's going on in JUMP or tanks ARE interested and fan response across the ages has been quite popular to the current arc. I haven't heard much criticism of it, actually not any on the JP side.
The anime adaptation of Zou started strong with stellar art direction and okay pacing, but now three chapters worth of content has been stretched over four episodes.
Despite the drops of new information revealed, things aren't moving. The Straw Hats spend over three episodes in one room and for a casual viewer, they would find that extremely boring.
Which, for me, as an adult fan this is a problem. But for the target audience (which according to commercials is divided between elementary students and 20-30-something females) -i.e. Gin, Ace, Marco, Law, Thatch, Sabo fans- who aren't familiar with the entire story (it's not uncommon for fans to 'like' the series but not own the whole series) it's a necessary evil. I don't mind the explanation stops. It's the ooc slapstick and silent shock pauses that kill me.
