I'm probably in the minority but I seriously dislike this.
First the part about Luffys Devil Fruit suddenly being something else than what we were told for 20 years, secondly the fact that its actually this hugely overpowered, legendary one instead of just a random rubber fruit with a very creative user. This feels super naruto "your the chosen one" like, which I really dont enjoy as a trope
And then his whole new look and personality just feels way too cartoony and funny, even in the OP world. I dont know, maybe Oda manages to catch me in the following chapters, but this one was a huge letdown after two long weeks of hype
