And agree on the sentiment that despite good reviews, that this won't go until the long season ....I still say the furthest arc that they could have go from here is until the Arabasta Arc when the Mugiwara crew defeated Crocodile and his gang.
Not to be pessimistic but unless Netflix pumps a lot of money into this (assuming they can commit long term to this IP), I just can't see how, especially the further arc will get translated properly.
The long term future of this show imo, is not how long the story really was (just like others already pointed out, a 100+ manga and 1000+ anime episodes)...but rather if Netflix could commit financing and pumps a crazy amount of money into this IP going forward. And given the more crazy the story, the world and the characters as the story goes...I just can't see Netflix would adapt this into the very end.
I mean...how do you translate Luffy in his 4th Gear and 5th Gear form in a live action?
And also Kaido in his Ryuu (Dragon) form....and Big Mom who literally has a Kaiju-size body shape..(and also Shirahoshi, also a Kaiju-size Mermaid..lol)
