Well, the way I see it, Oda had two options
a) he could make Sanji reach heights his shit family couldn’t even dream of, through his own powers like Haki and things he learned from Zeff and Ivankov, people who actually cared about him
b) he could make Sanji reach heights his shit family couldn’t even dream of, but having to rely on the experiments of said shit family, making me wonder if Judge did have a point about him being a failure after all.
Can’t really fathom why he went for option b, I know it’s a kamen rider reference but it doesn’t half leave a bad taste in the mouth. It’s literally all thanks to Judge and Niji that Sanji isn’t dead right now. The justification being “Sanji still has his emotions so Judge was wrong” and “science is the power of mankind” isn’t really enough to answer my distaste for the whole thing.
Also doesn’t help how boring and one-dimensional the Vinsmokes are. If you’re going to have Sanji struggle with his family heritage, you have to at least make that family slightly interesting and not card-carrying villains. The only slightly interesting thing Judge has ever done is cry at the Tea Party.
