Okay, so I am a massive One Piece fan. I'm caught up on the manga and anime. Watched all 15 movies and even visited the theme park in Japan. I thought the idea of a live action series was stupid but was willing to check it out to give it a chance.
While I think it's overall okay (not amazing or terrible), it's better than the majority of live action American adaptations of anime. You can tell the creators actually care about the source material which is the bare minimum these days. I have some issues with how certain characters are portrayed (biggest one is Nami) but I was impressed that this wasn't a complete dumpster fire. The manga is 10000% superior to this adaptation though like it's not even close.
