There were tons of capeshit movies in 2006. Superman Returns and X-Men 3 were two major ones that year. If you look back to the rest of the decade before that, the trend was already huge. Two X-Men movies, two Spider-Man movies, a Punisher movie (not counting the '80s one since it was before this boom), a Hulk movie (again not counting those TV movies since they were before the boom), a Fantastic Four movie, Catwoman, Batman Begins, Daredevil, Elektra, and I'm sure more I'm forgetting. Also Blade, but casuals didn't even realize Blade was Marvel, and just saw it as a cool action vampire movie. And that Man-Thing movie, but I don't think casuals even realized that existed. The point is, I hate when people act like the current boom started with Iron Man. Iron Man was just one more superhero movie among many. Nerds thought it was cool when the second Hulk movie (which casuals figured was a sequel) had a cameo to establish a shared universe. (The Spider-Man tv show that tied into the movies already had Michael Clark Duncan Kingpin to establish it as a shared universe with Daredevil.) But really it wasn't until Thor and Captain America, characters casuals wouldn't care about on their own or due to their stars (no RDJ comeback star-power) that they had to market more on the shared universe and promise of the upcoming Avengers movie and people really started to care about the MCU as a thing. The superhero movie boom started way earlier. And of course there were the Batman movies in the '80s and '90s and Superman movies in the '70s and '80s, but I won't say they started massive superhero movie booms. They had their own influence, but not specifically for making superhero adaptations, or at least not as many. Batman might have influenced things like The Crow, The Phantom, The Saint, and The Spirit (the movies. I know several of these characters predate Batman), but that's not quite the same as X-Men obviously directly influencing Spider-Man, Daredevil, Punisher, Fantastic Four, Ghost Rider, Iron Man, etc.
>When will it die?
It died after Endgame. Everything since is its rotting corpse. The HIV that was Captain Marvel became full-blown AIDS after Endgame.
