Regardless, I do feel like these guys tried their best. Even if it ends up being cringe and bad, I do feel like they tried their best to make it good. Adapting manga and anime into live action and making it good is next to impossible.
I think they should change things
A lot of the things like the hair color, looks and the visual gags that work in animated format will not translate well into live action
You should tone things down
Luffy can be a joyful teenager and you can write specific gags that will work better for the show but you go overboard and it makes it cringe like we saw
Fans might complain at first but if you make a good show they'll come around
Well anyway hope it's not too bad
