Okay my two cents. No i am not excited about Live Action One Piece as much as I would like to be.
OP is too long to be adapted into LA. Obviously they are not going to adapt every Arc up until Wano or Egghead, that would cost trillions of dollars.
I do wonder how many episodes or "Seasons" / Arcs they will adapt. It would be great if they made it to Alabasta, because after Alabasta the OP craziness sets in and we see a new world of diverse characters.
Netflix being netflix I can see them doing one season of 10 -one hour long episodes. I can see the East Blue up until Rogue Town before the GL being the end of season 1. Ideally they should not take too long per episode, like the anime lol. Morgan and Alvida can be handled in the first episode. Buggy can take 2. Usopp and Kuro maybe 2. Baratie another 2, Arlong Park maybe 3 and Rogue Town 1. That makes exactly 10.
But then after Season 1 is done and if they want to continue it, then we'll have to wait another full year for another 10 episodes. I do not enjoy waiting that long and that is problem with Netflix. They take a whole year for 10 episodes. The episodes are great but the waiting time is too long and by then the actors get older or stuff happens.
Another huge thing that I am not looking forward to after seeing a few glimpses is, anime can not be fully adapted to live action. Animes have characters with wacky designs, green hair, orange hair, pink hair, long spiky blonde hair, monster-like appearances, etc etc.
Buggy looks hideously creepy and thats not something you expect from seeing him in the manga but in LA , it scared the shit out of me and not in a horror funny way. How will Arlong with his saw-like nose look like or the rest of the Fishmen, I feel like they will look creepy AF.
Imagine Moria or others.
Also while the Sea King from chapter 1 looks menacing and huge and cool, I think they over did it. They put too much effort on it. Because now I can only expect for the next Sea monsters to look even more terrifying and awesome. Especially the Neptunians.
The gum gum pistol punch looked wacky and honestly if the fighting scenes are not the best part of the LA at this point, then they have no business continuing because as we all know, East Blue is the basic of basic fighting. it ain't until Enies Lobby that we see the action spike up to another level. If Netflix cant get it right in the East Blue then I have no hope.
The only way to improve it would be to hand off the rights of production to Disney/Marvel. Say what you will about them but when it comes to CGI and LA of comics, they do an amazing job that has no equal. Look at Pirates of the Carribean, Davy Jones and his fishman looked great.
Marvel Avengers have CGI that is out of this world. They should be the ones to be producing One Piece Live Action.
