One Piece isn't shit. The way Oda plots out the story carefully, and foreshadows and all that is amazing. Sure, One Piece follows the formula, but it's a Shonen... So is Hunter. Who really cares in the end, both are going to have their cliches.
Listen, I wasn't the one that said Hunter was shit either. I think it's good... Ish. And I also said I can see the appeal of Hunter, too.
I also think One Piece is overrated, too, just a little (Hell, I used to be a fanboy)... Just like Hunter. Hunter is moreso, however. That is my opinion, you don't have to agree with it.
The reason I base this opinion is because people criticize things like Part II One Piece (I don't entirely blame them). In Hunter, people don't call it out as much for being overrated.
Also, just because One Piece is more popular, doesn't mean it's more overrated. I've noticed Hunter is more well-received among anime fans than One Piece... That's why I think it's more overrated.
Maybe I should have been more accepting of your opinion on Hunter, but by no means is One Piece shit.
