Is it?
I obviously like superhero movies hanging around here, but honestly, I feel like the way the general audience has cooled on the genre and especially the MCU model of an interconnected universe content farm is for the best.
There is such a thing as too much of a good thing. It's been nice to see other genres re-asserting themselves and a more discerning audience will hopefully drive up the quality of those superhero films that are still made.
Personally, my hope is to see more of a return to filmmaker-driven solo franchises like Nolan's or Reeves' Batman trilogies.
