That's the thing though, ironman being the main charachter is simply because he started the whole thing. If his movie flopped the Mcu as we know it would never had happened. And as to the avengers yes it's the ironman show but thor, captain america and wanda were given their due. Hawkeye and black widow were all given their shot not as well but still they were given a shot. Each had a trilogy to let us know who thy really are. Same for most of the members and other charachters. Even dr strange is now a household name before 2016 had you ask the random individual who he is they will look at you funny. Wanda controversial casting aside due to getting the chance to shine as she should in the mcu has proven to have the potential to be just as big as thor and the like. Captain marvel as much as they hate her is the most popular female superhero in the world along with wonder woman. Guardians of the galaxy is a household name. And so on and so forth all because they were given a chance.
Like the mcu gave relatively obscure characters the chance to shine. And proves that a charachter isnt inherently popular they simply need good stories and exposure and they will be big. And with the xmen they have a gold mine literally! Hence why I say they should cool it with the wolverine stuff and start focusing on all the other xmen because them focusing on just one charachter, pushing all the good stories and exposure to just him is a very foolish business move. Like planting seeds in an entire field of corn and just watering just one and expecting a full barn harvest.and taste wont happen. Even dcu knows to diversify their portfolio and they have the most iconic trio in comics. I speak on storm because I know her best, but the other xmen also have such gargantuan potential it's crazy that their entire world is wolverine wolverine. Like you want an assassins creed type franchise gambit is your guy. The thieves guild and all that. You want sherlock Holmes well we have irene and mystique there. You want a midevial crusade epic bennet du paris and En sabah nur are looking at you. And sooo much more.
Anyways the main test for disney is the upcoming animated series. We will see how well they translate xmen to screen.
