Don't want to be mean, especially since I've only read 42 chapters on the 1000+ that make up One Piece, but I found it boring. I did read Inuyasha, Naruto, One Punch Man and even Bleach religiously, but I was younger and had a lot of time on my hands. This one is just another "young male teen with no actual connections meeting friends and enemies and leveling up" story. And it's also very childish.
I enjoy shōnen manga, but this is just too ridiculous for me. I understand it gets better later on, but I've skipped somewhere in the middle and it didn't seem to. Anyway, I guess I can category this as DNF and move on with my life.
