I'm not excited for Sam Wilson as Captain America, and I'm not excited for a female Thor.
Now, I don't think these are totally wrongheaded things to do. I admire the impulse behind these changes, and I believe they come from a good place. In the abstract sense, I love the idea of Marvel featuring, in big, bold style, the adventures of a black man and a woman against the hordes of iniquity. I believe at least part of the motivation behind these changes is genuine in its altruism, and that it is not entirely invalidated by profit-seeking impulses. I want to believe in this initiative. I want to be excited. I do not want to be the curmudgeon in the corner, needlessly nitpicking everyone else's good time to pieces.
But it feels like a gimmick, and functions like a gimmick, and that’s because it is a gimmick. I give it perhaps two years — two years that only the most hard-core aficionados will end up able to recall, alongside their recollections of the foil covers era and that one time Doc Ock was Spider-Man.
