This, x-men and spider man are as much popular for the great animated series kids saw in the 90s as they are for the movies. Iron man and Black panther were virtual B lists if not C in Panther's case and both have gotten a level of popularity they never had before. The MCU will be well known in the future alone for bringing lesser known characters to the forefront. While sony and fox basically used well established characters that had popular series preceding their movies. IDK how someone could think that isn't impactful or meaningful.
This as well, that why it cool to see Netflix get millerworld. I am not that big of a fan of it but I am willing to become one with the shows are good. We need more big money getting these unknown brands and making them big. The way disney did with lesser known marvel characters. At this point sony has mixed results even with a money printer like Spiderman. And let's not even start with fox and the Fantastic four. The unknown comics are unknown because no big companies want to bet on them. That's killing creatively more than disney owning marvel properties ever will.As far as other comic book properites outside of marvel and DC... they exist. They're not as high profile and won't necessarily get you a billion dollars, but they are out there. And hopefully they get to see the light of day too. Not that I blame Sony or Fox for wanting to use Marvel characters over something from Image or whatever... just saying what I would prefer seeing. Marvel does a better job with their characters than anyone else... so let them use their characters. Other studios can bring to life other comic book IP's, which deserve it too.
