I love superhero movies. The movie coming out in the next couple of years I’m actually most excited for is actually The Batman, followed very closely by Thor: Love and Thunder. But I also expect them to have interesting, engaging stories with character development. Into the Spiderverse, Black Panther, Incredibles, Logan, Big Hero Six... shoot even Tim Burton’s Batman, run narrative circles around any of Nolan’s Batman films. And they’re proof that you can (nay, should) have a half-decent story for your superhero movies. Hugh Jackman tried his hardest in Days of Future Past. It had some of the best actors available and was competently made. The story was crap though.
Popular media in the 90s revolved around Batman, X-Men, Teenage Mutant Ninja Turtles, and Power Rangers. All superheroes. Blade came out in ‘98. The X-Men came out in 2000. Spider-Man was 2002.
Those 80s/90s kids (hi) have, unlike previous generations, dragged a lot of the things they loved as children with them into adulthood. They’re willing to un-ironically publicly claim their fandom. Batman and the Joker were ALREADY popular. It wasn’t Nolan. Blade, Raimi’s Spider-Man, and Iron Man did far to push superhero movies along because they actually proved good movies with (at the time) “lesser” characters could succeed.
