For me, it has to be either thriller bark or fish men island. i feel like they both could’ve been better. thriller bark had a lot of funny moments, lola, brooks first appearance and obviously the “nothing happened” zoro, but tbh that was the only good things abt the arc and the pacing was quite slow too. i guess it is important to the show cause it shows zoros loyalty and brooks backstory but the story overall was not the best. fishmen island arc is even worse. it plays an important role to the story but there was nothing interesting to like about the arc. we learnt more about the ancient weapon and also jimbei, but nothing else. the villian (hody) was also horrible. he’s not unique at all and nothing interesting. he’s just an average fishmen trying to fight luffy.. i was honestly so stressed when luffy and the other straw hats couldn’t defeat them in a minute? like damn y’all trained for 2 years just to spend so much time on these wannabe fishmen pirates? 🤦♀️ the pacing was obviously also slow, but that’s already normalised in one piece. the title “fishmen island” sounds so much fun and interesting but overall it was boring to me. no hate to thriller bark and fishmen island lovers though!
