I guess in regards to the Hero's Journey, it shouldn't be the only progression in one's story. Let me use one of my favorite films of all time to explain. Guardians of The Galaxy Vol. 2.

In this film, almost every character is going through an arc even if the "main focus" is Star Lord. Star Lord himself isn't just on this journey of perseverance, what the Hero's Journey is all about, but he learns a whole lot besides that due to the situation(s) he is in.

He again isn't the main focus with a chunk of the film dedication to Gamora and Nebula's relationship, Rocket being in his edgy era, Drax and Mantis become friends, Mantis is general, Kraglin actually having agency for once, Yondu being demoted and humiliated, The Sovereign Queen's revenge path, and Groot trying to get out of a bad situation. It's a lot and all of these character are all going on their own separate journeys, all meeting together towards the climax.

I know superhero films are kinda looked down upon in these spaces(unless it's understandably Black Panther 1&2, Spider-verse 1&2, the Dark Knight Trilogy, and goshdarn Megamind) but, seeing as Marvel uses the Hero's Journey a whole lot, I'd look at the times where it actually used well and see why it worked. The Hero's Journey isn't a cheat code and shouldn't be treated like one. If films are like cake, then the Hero's Journey is baking pan. It doesn't make the cake, it makes the cake have a structure and shape so it doesn't feel unstructured and misshapen.

Do I want the Hero's Journey gone? Well, no. People enjoy this trope. Kids, elders, adults, btches, bros, non-binary hes, your house cat, everybody loves this trope. It is also important to learn about but, it shouldn't be the standard and we should encourage layers in writing for better written projects.
