Zoomers and millenials don't give a fuck about superman, they didnt even watch his movies growing up
unlike spiderman
I don’t know any millennial that didn’t grow up watching Justice League and Justice League Unlimited.
Even now Superman media may not be as common, but that’s because the Superman clones are absolutely everywhere. Omni-Man, Homelander, Sentry, Metro Man, hell when DBZ came to America the dubbing team made Goku more like Superman to appeal to Western audiences.
Superman/Clark Kent is the face of Superheroes. Even Spider-Man’s color scheme is based on Superman.
