That's an interesting thought. What if the actor cast for the role wasn't cast because she was black? What if she was cast because she was the best actor to audition for the role, and she just happens to be black? Would it still bother you?
Well, I AM assuming she was cast because she was the best actress for the role. I would like to think the director didn't see her and think "It would be great to start a controversy so I'm going to choose a black Hermione in order to draw attention to my work even if she is a terrible actress and any of these other women would be a better choice".
I would assume the director either thought "This actress is the best that auditioned" either without thinking of her skin color or thinking "I know the original Hermione in the films is not black, but despite that this is the best actress that auditioned".
So to answer, yes, I would still not like it, but I would understand.
