@waitworry no, it's for a number of factors:
1) there was a much larger variety of superhero stuff in the 90s, not just the indie comics (altho there was a lot of that too), but like all the different knock off superhero films and games too, and a lot of people trying to make their own superheroes whether creators or fans, that creativity is imo very important to "superheroes"
2) and all of the superhero stuff, even the bad films people make fun of, still were about being a superHERO: having a secret identity, wanting to save people, wearing goofy costumes, even something like Mystery Men had a lot more heroing in it than stuff now where people are superheroes as jobs or have superpowers but actually are doing other things than being a superhero (or even wanting to be a superhero)
