In today's politicized cultural climate, people sometimes like or dislike the concept of a comic or movie without concerning themselves with whether it's actually good. Frequently with comics, they only know the concept, and have no intention of reading the book. Comics have become pretty niche.
But with a movie it's different. They will see the movie. If there is any controversy, it's only after the movie has left the theaters that partisans will take a less heated, more dispassionate view.
People on the right suspicious of a possible left wing political agenda with the Black Panther can then, after it has finished its run, admit that the movie was good. On the other side of the political divide, defenders of Captain Marvel, after that movie had run its course, can admit that it could have been better.
The Iceman solo comic which explores Iceman as a newly out gay man gets cancelled because of low sales, and the New York Times rights an article about it. So it gets un-cancelled, but people still don't buy it, and it quietly gets cancelled once again, and this time no one really cares.
The whole situation sucks. Everything is seen through the lens of the culture war. Fiege will have his work cut out for him in the years ahead in maintaining a undivided fan base for the MCU -- something the Star Wars franchise has failed at.
