Even if the next 8 episodes are 8/10 in quality (highly unlikely), it's still too late. Th damage has been done. Many have lost interest to the point that they dropped the show. I even saw reactors dropping the show

like you know shit is bad when the people who get paid to react to anime episodes don't even wanna watch the episodes.
Just being a big IP doesn't mean much anyway. Berserk got even worse treatment than OPM.. same is true for many, many other series like Seven Deadly Sins and Tokyo Ghoul.
The best case scenario is that some other studio/company gets ahold of the IP.
Though even then, it would just be a bandaid because the JC Staff portion is so bad. I guess the absolute dream scenario would be that a studio picks up after S1 and redoes the whole thing from there, but the chance of that happening are abysmal. Especially in the next 10 years lol.
I think it might just be dead. Even if we do get more anime, it'll probably be 5+ years down the line....
