Both you and the author of this Twitter post have a point. Wano is full of shit, but every other arc is as well. Asspull PUs? Every PU in OP is an asspull, especially those from Enies Lobby (the most wanked arc in the series). No deaths or insignificant deaths? Tell me one arc aside from MF that has ANY deaths. No tension? Same as deaths. No real Kaido flashback? Doffy and BM are the ONLY villains who actually got a flashback longer than 1 chapter. Villains don't usually get flashbacks, and the juicy part of Kaido's flashback (the one with Rocks) is probably something oda is saving for later.
Most other criticism I see comes exactly from what Twitter post wrote, headcanons, theories and agendas. People are butthurt that Wano wasn't Zoro's arc. I was disappointed as well, I had multiple scenarios for Zoro to shine in this arc in my head (no delusional shit like ZKK), but I guess that isn't how Oda imagined HIS story. I was disappointed yes, but bashing the story and the author for not doing something I wanted to happen is a bit ridiculous.
Rereading the arc doesn't fix Big Mom being annoying asf this arc and a huge plot convenience, it doesnt suddenly make Queen competent, it doesn't fix Usopp's shitty treatment lol
And that's exactly the point of this Twitter post. Why shouldn't BM be annoying? Why should Queen be competent? Because that's something you wanted them to be? "That character didn't turn out how I wanted him to be" is not a valid criticism. People think of Yonkos as some all powerful gods of OP (similar to what Madara was in Naruto) and got disappointed when it turned out they are just powerful but not invincible. Akainu said it himself in back in MF, Yonkos are losers. Even now, we have Buggy among the new emperors, which is just further proof that they can be frauds.
What did Usopp do in Fishman Island? Punk Hazard? Skypea? Not every arc can have every strawhat (that isn't M3) shine, especially now when there is 10 of them.
There are a lot of things I didn't like about Wano (not the best, but not the worst arc either, somewhere in the middle) but most of them are related to pacing issues. I've been reading this series for 12 years now and I had a lot of theories and headcanons of my own, most of them never came true, and the actual outcome was sometimes better than what I imagined and sometimes worse (in my opinion ofc).
This is why you, me, and most of the fanbase probably enjoyed preTS a lot more than postTS. Because in preTS we didn't have a road map, we didn't have expectations, anything could happen at any point and everything is a surprise.
They just defeated Crocodile and left Alabasta, what's next? Did you have any idea what next arc would be about? Did you expect a 400 years old ship would fall from the sky which would lead to an adventure in the sky island and pit SHs against a self proclaimed god? They left the sky island, what's next? A train riding on the sea? A city on water? A secret organisation that was never mentioned before and was introduced in the same arc it was defeated in, thus not giving people too much chance to dive too much into the sea of expectations and headcanons?
Now this is my criticism, not only for Wano, but for this entire saga:
Ever since PH people have something like a checklist in their heads for things that HAVE TO happen in order for them to be happy. Everything SHs do is a part of a plan to thwart Kaido, characters are introduced too soon (before they actually get to do something) creating expectations and headcanons. We know what the story is heading towards (Kaido's defeat in this case) and we start creating scenarios in our heads much sooner than we should and get too attached to those scenarios because they sound awesome in our heads. We start overanalyzing everything, having agendas, wanting our favourite characters to shine, trying to find a secret meaning in things that have none (like Kokeshi dolls, giant sword in onigashima etc) and then, delusional ideas like ZKK are born. In the end, things don't go the way we thought they would and we feel scammed, because we believed something that was never meant to be (like Queen being competent or BM being invincible). In this case both Oda and community are to blame. Oda for teasing things he does not intend to deliver upon, and community for taking the bait.
Fortunately, this will end now after Wano is over. Once again we won't know what the next destination will be and what awaits the Strawhats, and OP may finally have that "adventure into the unknown" magic it used to have.
TL;DR Oda is a clown but so are you :cheers:
