I don't want to start a beef. This is page here sort of summaries why Sanji is forever relegated to being my least favorite strawhat.
And no, Sanji has never changed from this sort of mind set. His own dreams change and are given up on multiple times and it's used as gags even by Oda how wishy washy he is. Also his dreams are generally lame so there's that. (But this is a personal thing since who cares about all blue whatever)
Again I'm not trying to cause a disturbance with unfounded jabs thrown at everyone. I've seen people who plainly dislike Chopper being cutesy or Ussop beige a coward. These are core personality traits written into these characters and they will never change and I can't start arguing with a person if they just plainly don't like traits like cowardice in their characters. Same as people who don't like Zoro's badass aloof stuff. Its just preferences and such.
This page stands as the quintessential I remember not checking out Sanji from ever being even in my top five and he just kept going lower and lower from there
