Why are you playing dumb? That's how franchises work, thats how comics work, they switch actors and characters all the time. You pissed at Dr. Who? What about Batman? Some of those movies completely rework the character/backstory.
This happens all. the. time. without much worry at all. The only difference this time is that a minority group is getting the spotlight for like five fucking minutes while a bunch of idiots whine about it.
I fully realize how worthless a conversation this is, but it's funny to see you reach for any reason to remain hateful.
People that acted as Batman at one time or another who were not Bruce Wayne:
Dick Grayson, Terry McGinnis, Damian Wayne (Bruce's son), Azrael (thanks Zoolander, you really are more than really really good looking)
People that acted as Superman at one time or another who were not Clark kent:
Zod (fun one), Harvey Dent (really though), Kal Kent, Lex Luther (another fun one), Jon Kent, Conner Kent, Val-zod, Kenan Kong, Kal-el, Calvin Ellis
People who acted as Iron Man, who were not Tony Stark:
Weasel Willis, Mary Jane Watson, Ultron, Iron Lad, Pepper Potts, Norman Osborn, James Rhodes,
People who acted as Captain America who were not Steve Rogers:
Bucky Barnes, Danielle Cage, Sam Wilson, Misty Knight, John Walker, Peggy Carter,
I feel like that's good enough. You think you got me with 007, but that's based off of novels and not comics/sci-fi. And either way, clearly you're ignorant to how fictional media functions, specifically relating to comic super-heroes.
