First of Frantz, I don't even know why you lurking in this thread. You already wrote off the show. I think it is your best interest to block it out of your mind and not let your intrusive thoughts win. I am sure there are plenty of other things to do then keep on spiral over things you don't care about.
Onto korwink, I have no idea how old you are. I have read One Piece since 1999. Heck I taught myself how to read on Dragon Ball, Doremon, Dragon Quest since 1994. I grew up not having a tv. I used to watch my neighbor's television through a fence. My country (not the usa) was poor then. We imported stuffs all over (Russia, Belgium, USA, Canadian, China, Japan, etc). Some of the things I watched then was not recent to said 1994-1999 but from the 70s, 80s, or even earlier. The stuffs that give me joy. Like said the famous and much beloved 1986 Journey to the West. Power Rangers. The canadian tv show of Sinbad. There are series I don't even know the name off. Dinosaurs are literally plastic props. Godzilla used to be a guy in a custom. Or even tv shows that blew people's mind back in the days like Heroes, Arrow, Flash, are outdated by now. Oda mentioned Shaolin Soccer as the movie that made him think a One Piece live action could be possible. And that movie is really also outdated.
If you want good shows. Check out Severance and Silos.
But yeah, if you want people's opinions. Scroll through this thread. Look at the comment section on youtube, or reddit. You got all the answers to your inquiries. Nothing you said are new concerns. All you do is merely look and you see thousand comments about how cheap and plastic Mihawk's swords look. I watched some smith and metalwork youtubers, and even them can not make those gems on Mihawk's sword looks nice.
The length of One Piece is still very off putting to people. This is a good entry way. I could see a lot of little kid like what I was in the 90s, gonna love this live action. And may try watching the anime, which now feel outdated compare to the flashy Demonslayer Yaiba, JJK, and the likes.
I guess, I am old enough to put things in perspective. To know HOW GOOD we have it now. I barely have money to buy a comic on Thursday. I have to literally walk to a manga stand to buy. And now, people can read million of things at their fingertip and still complain about it. I have to watch a tv show (that is an adaption from a book) through a fence. With cgi that make you nausea nowadays. And that was joy to me. This One Piece live action had blow all expection out of the water. The One Piece fandom are not deaf and blind. They can see everything that you see. Many prior to this week, keep their expectation low. Because they desperately don't want to hate it. They want to enjoy it. They want to like it. They want the show to have at least season 2.
I don't think your post is about inquiries. Because you can get plenty of inquiries by listening, and looking, and reading comments. You merely want to share your opinion. And that is my thought on your opinion. I wrote this tv show off ages ago. I only start to get hopeful this month. I don't want pessimism thoughts to hijack now. Especially when Oda really care about this. When tv/movie adaption had historical trend of in conflict with their authors.
