It's been a weird ride. They started superhero movies a long-ass time ago with the campy overly-triumphant stuff, then it died for around 20 years and came back with the gritty darker films like Batman, then THAT turned campy and everyone else tried to do the dark gritty thing and ended up turning superhero movies in a dark angst genre with Spiderman and X-Men being the only one not following suit, then THAT got fucked up with 3 and Iron Man came out and threw us into the current era. It'll eventually hit a ceiling and come back down, then return again in a few decades. Thing is, if these leave then something else has to take the place of the summer blockbuster, and we don't have a lot of young-ish action stars left. What if the end of superheroes gives way to the era of summer romance?
