Yeah, Wano for me is sitting at a solid 2/10 so far. It's almost like you can't go a chapter without something blatantly stupid appearing. Just look at this chapter. Even when you ignore the plot inconsistencies regarding Kanjuro being the traitor, and give Oda the benefit of the doubt and take the reveal for what it is, even that was done so poorly with an unoriginal explanation and an even more pathetic delivery.
After a 15 chapter bog following the lives of some of Oda's worst characters, a total change of events is exactly what's needed. It's very, very hard to feel anything or root for these characters even in the slightest when they're just so goddamn retarded. The straw hats have become far more unlikeable post timeskip, but the scabbards, Oden and Toki were something else entirely.
I've already given up hope on this arc carrying any real emotion or meaning given how poorly handled the pivotal flashback was. Can at least hope for some "cool" scenes in the battle though to try and salvage this arc.
