it's just a stagnant industry because the primary producers are big legacy companies that don't allow any real innovation
Which was needed DECADES ago. Really thinking of American Superhero Comics the biggest cause of their fall... was the fact that they refused to actually change their approach.
Like you can do stories that never stop, we see that in newspapers all the time... the problem is that they completely removed that approach around the 90's and refused to have the characters actually age, grow or new characters slowly get the buildup they need to actually earn their spot.
You still had multiple writers when that's a trainwreck waiting to happen when it would have been best to only have one writer do just one storyline or stick to their character.
For all of Manga and Anime's faults, there's very rarely someone swapping in for the author unless they died and they wanted the series to continue under someone else; There's very rarely consequences that don't matter because another writer came in and wanted to use a character and completely destroy the point of a good arc(Kid Loki is the biggest example of this); Characters actually grow when it happens and don't regress because another writer wanted to "start over" and so on and so forth.
The fact that this still happens and no one in the American Comics Industry understands this despite Japanese Deadpool and Joker Manga have equally sold far more than most of their shit is what makes this ridiculous and infuriating.
No wonder people don't want to care about the X-Men when Krakoa goes against everything they stand for.
Why bother with Captain America when the writers clearly hate him and America?
Why bother with Black Panther when they shit on T'Challa everytime because Storm left him?(No, this actually happens now)
Why bother with Batman when he's still bitching that Catwoman left him on the altar to the point of savagely beating Jason Todd for using blanks?
Why fucking bother with Spider-Man with
everything they ever do with him?
Even with us ragging on My Hero Academia, One Punch Man, Negima!, Bleach and all of that other shit, those are STILL a THOUSAND TIMES BETTER than what's going on in American Comics for the past 20 years alone outside of some very rare outliers.
