The best part of One Piece was Oda taking seemingly "weak" Devil Fruits and making them look hax. Rubber, Mochi, String, Cracker. That was real creativity.
Now he's essentially said "fuck it". Why be creative? Just have a DF that can be anything and all things. Then you can justify any stupid bullshit you want. Like a preschooler coming up with a story.
I said last week that One Piece has been taking a nosedive since TS, but this was the final nail in the coffin. This story isn't for adults, nor middle schoolers. It's for 3 year olds.
