What is insane to me is that Oda goes out of his way to actually DRAW panels of moments of Sanji's "self-deprecating" nature, to show us that it's something since his intro in BARATIE, but you would have people think it came out of nowhere.
2 and a half chapters just bringing everything back together and taking it's time to show everything.
He even went out of his way to show how Sanji's kamabakka period wasn't something "just for the gag" and tied it into his development.
It's INSANE how you can call that "bad writing".
It's not gonna win any worldwide writing prize contest, but holy shit it is far from "bad". lmao
