Zoro got lots of cool feats but the story was not satisfying specially how it was concluded. Kaido deserved a better death than getting blown up by a volcano. BM got ridiculed the most to the point many people consider her the weakest top tier or scale BM in two different variants a PIS variant and a 3 Day battle with Kaido variant.
He introduced too many characters and was unable to give them the panel and story relevance required. Oda could have literally made Orochi a strong villain on his own and have Zoro deal with him and have Luffy defeat Kaido or some variant of this. All the hype for Wano Samurai and we get one Ryuma (legend) and one Oden (recent past) and then a couple of YC level guys (present).
Death is what completes a person - no conclusion
There wont be a monster samurai like Oden - no conclusion
