I think superhero movies peaked with The Winter Soldier because they were concentrating more on a good story rather than just explosions and CGI. They built up so many long arcs that ended with Endgame and they’re struggling to start new arcs now because the original MCU characters were just too good. It’s hard to get invested with the heroes in the new movies because they’re too concentrated on milking cash than starting a new long arc that will last over several movies and team-up movies. It’s sad but I don’t think it’ll come back at this point. Not even going to mention the dumpster fire that is the DC universe. I loved The Batman though and hope they continue with that theme.
