1) The general demographic expects and supports diversity much more than it's comic book counterpart.
2) The current comic book team placement is heavily caucasian driven. Which in itself will make Marvel look bad if this exact
extraction from comics to the general audience (no matter how many complain here, Avengers would have made a lot less
money IMO, if Nick Fury was not around, as an all white team for being the "world's greatest heroes" would be rather off putting for many.
Thus, they change the races of certain characters in their movies.
3) Their movies are a big hit, and have possible capabilities of bringing new readers to read comics, yet the issue would come into
bare that if some is coming to read about Samuel L Jackson in a comic (which is quite possible), they would be heavily disappointed
to see the Nick Fury in comics being rather different than the movie counterpart.
Now, how this could have been solved is by having more popular minority heroes in the MU, as seen with Luke Cage. With Luke Cage
transition to a higher position, we are seeing him in many different places in the regular media. But this is due to Luke Cage
essentially leading one of the top selling MU books, New Avengers. If other books had prominent roles for minorities that sold well,
or even more so, comic books that sold well, they would use those characters in movies instead of just race changing already
well known characters.
I never said it's entirely the reader's fault. But it is the large portion. The writer and creative team can only do so much, as there are plenty of books with minority character solo booksAnd considering Marvel's premiere Black hero has been crappy ever since Priest stopped writing it, and other attempts like Blue Marvel fail to compel readers,...it's not entirely the reader's fault if a writer fails to capture the audience...it's usually the creative team's responsibility to overcome those hurdles.
that has received decent to excellent reviews like Blue Marvel and Batwing. But the problem is these sales start of low, and just end in cancellation. Which shows the problem primarily
wouldn't be the writer's fault, but the reader's fault for not be willing to give it a chance in the first place. In other words.
Black Hero starts off with very strong sells but loses sales quickly and ends up being cancelled/ Writers Fault
Black Hero starts off with rather low sells and dies off very quickly/ Readers Fault
And unfortunately, the majority of cases that happens with minority characters happen with reason 2, not reason 1.
