I used to simply feel neutral on Sanji as a character and really liked his battles, but ever since that bullshit he pulled with Khalifa, playing tea party with her and toying with Robin's life I've came to despise Sanji, and that's not mentioning how lackluster his fights became since the timeskip.
By the way am I the only one that thinks that Oda somehow made Sanji worse with that sorry attempt of a character rewrite, that he's the "nicest guy ever"? What kind of bullshit was that?
