Such as?
You know, I keep seeing this repeated as if it makes it true. And as I've pointed out repeatedly, I'd like for it to be true, but it just hasn't been as effective as introducing "legacy" characters that build on the myth of an already established character.
Yes, we can point out exceptions to the rule (such as Spawn) but Spawn is an exception -- having an artist like Todd MacFarlane behind it -- and not the rule. The rhetoric about "original" or "existing" vs "legacy" is all well and good, but at the end of the day it's all about business and profits for Marvel. I'm certain that as much as Marvel would love to have a "Spawn" in it's gallery, there's no reason they wouldn't be just as happy with "Ms. Marvel" generating similar profit and interest, not to mention winning awards.
For those of you who think otherwise, practice what you preach and create an "original" character and see if you can prove what you are saying is true -- and note: I say that as someone who is attempting to do exactly that with the comics you see in my links below.
Honestly, I give Marvel (Comics) credit for making the kinds of moves it has been making lately -- it now has three of the top grossing films in history with majority all-white male leads, yet they are STILL trying to promote characters like Kamala Khan, Miles Morales, Gwen Stacy, Squirrel Girl, Sam Wilson, "female" Thor, Black Widow, Elektra, She-Hulk, Storm, etc, etc in their comic books...
...rather than simply milking (white male) box-office cash cows like Cap, Iron Man, and Thor to the point of making Wolverine look like a Stan-Lee cameo player, which is what a lot of businesses would do in the same circumstances (Batman and Superman, for example).
Let's try to look at this from a realistic perspective -- legacy characters sell, many fans want more diversity, and white male characters are currently killing at the box-office, so Marvel is trying to find a happy medium between all of the above, which I personally respect. There's an old saying about trying to please all of the people all of the time, and I think that certainly applies here when discussing the issue of "diversity" in comic books.
They have promised us a Black Panther and Captain Marvel movie in the near future along with a Luke Cage and a Jessica Jones series, and given their dedication to widening diversity in their comic books, I personally feel that they will eventually deliver on both those films and possibly films and/or TV series starring characters such as Kamala and Miles and Gwen as well.
So let's not keep arguing and fighting over the same thing over and over again, when as many here have pointed out, many of the new "legacy" characters are doing well while the original "legacy" characters are still around and in many ways are more popular than ever worldwide.
There's plenty of room for ALL of these types of characters (Tony Starks and Carol Danvers and Kamala Khans) in the Marvel Universe and we are all more than welcome to buy the comics that we like and not to buy those comics that we don't. At the end of the day, the market will decide but at least we now have the option.
Anyway, time for me to get back to practicing what I preach, and working on my own original "minority-led" comics, books, and film concepts, and here's hoping that many of you out there will do the same.
