That's not Domino anymore than that was Negasonic teenage warhead in the last movie.
NTW was in all of like 7 comic issues to my knowledge so it was easy for them to get away with screwing up that character. Personally I would have rather they used Hisako aka Armor.
If they wanted to cast an African American actress then I would have rather they race changed Marrow then completely change Domino so that she doesn't actually look like a Domino.
