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.
