Just Disney projected hitting 7 billion dollar blockbusters this year. Look at the titles - Aladdin, Lion King, Toy Story 4, Star Wars, Frozen 2, Avengers End Game, Capt Marvel. There is nothing new there.
I would say there are no new stories and there haven't been for a long time.
What is the Iliad if not a superhero movie? You have the world's greatest warrior, Achilles, a demigod, unbeatable except for his one super-weakness. Sound familiar?
Something I find interesting about all the recent superhero movies is that the battles are staged very much like ancient battles - soldiers in formation fighting hand to hand. This of course gives the heroes the opportunity to be heroic on the field. And again it's just like the Iliad.
