I hesitate to get into this scuffle as it can only end badly, but IMHO turning Jane Foster into Thor or changing Sam Wilson into Captain America feels "forced." Sam Wilson is already an awesome superhero known as the Falcon. It's not necessary to make him into Captain America. Who says that there always has to be a Captain America? If the old white guys are so yesterday, retire 'em AND their characters. War Machine is more than an adequate successor to Iron Man - I'd go see a War Machine movie in an instant. I'd love to see the Falcon in a stand-alone movie. There's a lot of potential with already established characters that doesn't require making a "new" Thor or Captain America. I suspect that few people were ever put out by Supergirl or She-Hulk because they didn't replace Superman or the Hulk. They were just variations on a theme.
