This was damn enjoyable as a massive fan of One piece I'll start by saying I've read through the manga twice. I watch both the English dub and Japanese version. And this show felt like such a love letter to fans. There is so much thought and care into keeping with the source material while also making some (not all) changes that feel natural that I can't help but feel pure joy watching this show. The casting for this show was immaculate, I think all the members for the main crew did a great job in bringing the often larger then life characters to a live action setting. I also have to give massive props to the actors for Buggy, Zeff, Dracule Mihawk, Shanks and especially Garp. Okay, let me talk about Garp now. His inclusion in this season was fantastic, maybe it's because I thought the actor who played him did such a good job, but he feels like such a natural inclusion. For those of you have read the manga or watched the anime you know that Garp only shows up in a cover story near the beginning of the manga and in two episodes near the end of the east blue saga which is where this show almost ends off at. But Garp isn't really introduced as luffy's grandpa until what would probably be the live actions equivalent of a season 4 or 5. I didn't know how I would feel seeing this character introduced so early into the live action, but he fit like a glove. He wasn't as dumb and as lovably goofy as his anime/manga version, which could be said for a lot of the characters ( Zoro and Luffy), but that's to be expected in a live action version. However, Garp's pride as a marine and as a grandfather to luffy. Are still very much there and I loved that.
Now for the things I didn't like, don't worry there isn't a lot. Most of my problems with the show are on a technical level. Some of the CGI wasn't great. I do respect the practical makeup and effects on the fishmen, but lord they were ugly. I remember seeing Arlong in the trailers and thinking yikes, however I grew to respect him cause then I saw some of the others and whoa. Other then that camera work was a big problem of mine. Why is it that in a lot of talking scenes the camera is so close to the actors face, when Nojiko is talking to luffy and the crew outside her house. All five characters in that scene got close up shots. Nojiko makes sense, she's on her side in her doorframe, but the other four are standing outside her house. You can even see the other three members out of focus in the shot when luffy speaks. Zoom out let the actors playoff each other show me theirs reactions in real time don't just cut to Zoro so I can see his reaction to what Sanji said.
The only other complaint I'd really like to talk about is episode 4 .This was the weakest episode in my opinion. This episode felt like the biggest change from the source material and not for the better. Maybe It's because Django wasn't in it maybe it's because there was no Usopp pirates. But I think for me It's because Koby and Helmeppos involvement felt so shoe horned in. They didn't do anything. They showed up said they were going to help, didn't help, then just left. Also, Zoro getting his backstory revealed because he was stuck in a well made no sense. Why not instead of Buchie and Sham throwing all three swords in the well Sham keeps the Wado Ichimonji sword cause it seemed rarer or special or any reason at all idk. And that triggers a response from Zoro when he wakes up to then climb out of a well to search for and find the sword he cares so much about. Letting you reveal why he cares so much about that one sword in particular. Just a thought. That scene bugged me as you might be able to tell.
All in all I thoroughly enjoyed watching this show. The Easter eggs, the references, the set ups for the possible future of the show. I think if you're a fan of the original source material I'd say give it watch there is so much to enjoy. I hope we get a season 2 just to hopefully see Jamie Lee Curtis as Dr. Kureha. Now it's time to watch it with the Japanese dub to hear the original voice actors.
