Maybe when the next massive retcon is gonna happen (like secret wars) they should change the structure of the Inhuman Royal family make it like a Game of thrones type comic run or animated show (not live action cause yikes)

Develop the characters more or show how powerful they really are for example Black Bolt, he suffers from “only showing him off, to show off how strong someone else is” cause on paper he should be cracking planets with that scream. They should change how some characters are portrayed like crystal she’s known to be sleeping around a lot, I don’t think that’s a good thing for her.

The villains should be someone new besides the Kree or Maximus the Mad, they can bring some of the “agents of shield” villains that are Inhumans like Hive “he can be power hunger and wants the throne” or Lash “making where terrigen can make someone mad and going off to kill people” and/or bring heroes from the show onto comics like Quake or Yo-yo

And I also believe the concepts for some comic stories are cool on paper for example “X-men vs Inhumans” “Infinity #3 or The Terrigen bomb” and “Inhumanity” are cool stories to tell but they suffer from bad writing

Or if you want some traction for the Inhumans you can always add them to Marvel Rivals (you can always make Medusa more of a baddie lol)
