I've been a reader of One Piece on and off for years now. The premise of "uhm actually, being a pirate is about having fun with your friends" is what kept me attached. Exploring the world with your friends while dodging the grip of a UN for Monarchs is a very cool premise. It's a really romantic version of piracy. In practice though the crew's journey seems to be them going to the most dystopian fucked up islands imaginable and doing a regime change. I feel like a different formula would've been cooler. But as the current president of the United States once said, I'll still keep drinking that garbage.
It's got an amazing world though. Water 7 and Skypeia are my favorite locations.

Critical support to the anti-imperialist Doflamingo for standing up to the World Government :fidel-cool: jk
One Piece feels a bit too much like the epitome of the whole "Making weird characters and powers just to be unique" thing that's present in a lot of action series which while I understand why it works so well, I just can't get into it. For every cool power like Law's or good design like Zoro, there's another like that mocchi man or big mama that just are snooze for me and just seem really weird and bad as if the creators ran out of ideas half a series ago and is just trying to come up with something off the top of their head. You see this in a lot with other shounen series, My Hero Aca has some really cool ideas like Hawk, and then they have "sticky ball man who is also a pervert" for no reason.
I'm sure I could analyze it more if I tried but if I can't enjoy a series at a basic level it's really hard to try to get into it deeper and care about anything else.
