Mythology has served various purposes over the course of human history. This is referring specifically to modern superhero culture which may be derived from mythology but isn't comparable to it.
There was a "making of" feature in the 1960s Marvel Comics where Stan Lee was talking on the phone and said "How can he say it was a cheesy story? I ripped it off from the best classic I could find!"
Similarly it's just as fair to say that Shakespeare was like Joss Whedon than the converse.
The first two seasons of Pretty Cure looked like religious education to me.
The first season was about Shinto and the second about Confucianism. The series systematically worked through about how you would feel about your place, your town, nature, the people around you, history, work, community, etc.
Cinema in particular is way more similar to temple sermons than it seems at first.
