Try got fucked by the director jumping ship to do My Hero Academia, which was set up from the word go to be a multi-season job.
If Sunrise had any faith in OG BF, they would've signed the guy to a similar deal.
The main problem the post-BF shows have had is lack of leadership with a good idea of how to channel the Big Nerd Energy the original did. Try kinda coasted for the first half of the show on the residual good will of its predecessor, but couldn't keep it going because the guys working on it fucked up by taking out all the first half rivals aside from Minato, so they had to whip up new jobbers who didn't have the same kind of beef with the main cast as the previous ones did.
Build Divers was trash because the writers and director didn't know shit about games and online fandom, so they couldn't fulfill the potential of their premise. Also, I think they changed writing teams entirely, because aside from Koichi's intro episode, none of them were particularly good at character stuff, while a few were okay to good with gags.
Re:Rise got around that by focusing on a single main plot and making the character arcs fit the plot. The main problem with Re:Rise is that if you don't care about Sarah, Eve as the core of Hiroto's emotional journey doesn't land, and for some reason, they played this dumb game where they would refuse to confirm things they implied until way later in the show.
