Squeezing all the juice out of a genre or subgenre is what Hollywood is best at. If you didn't like cowboy movies you were avoiding like 60% of all movies and tv shows made from the birth of cinema until the 70's. I think we're seeing the same thing w comic book movies. In other words they'll peter out, but probably after all of us are dead.
Really? Have you enjoyed the drek that has been released over the past decade? HBO started the bucking of the system, F/X and A&E followed. But since they were cable ops, I guess they get a pass? When Netflix started producing and pushed everyone's game, content started getting so much more interesting. Obviously, Amazon/Apple followed. I'm waiting for Google to get involved so we can have a full FAANG entertainment.
All of the Paramounts/WBs want to do is take the one franchise and squeeze every drop from it with endless sequels to the point I have completely lost any interest in explosions, cars, and super heroes.
