The same goes with the Fantastic 4 2015. We all have known Jimmy Olsen and Johnny Storm The Human Torch as a Caucaisan characters, so why all of the sudden make changes and turn them into a different colored characters? Again, I have no problem with any race or color whatsoever, but why the hell would they change a character's color completely?

Jimmy Olsen, as presented by the originators of the story, "Superman" was a young cub reporter who was used for comic relief. He was white. That persona carried through to the television version of Superman and comic books.
Supergirl was not developed by Siegel and Shuster. Rather it was a comic book offshoot of the original Superman. Therefore the development of the character on television as we see it now, has no relationship to the original Superman. Not only that but it has no relationship to the original development of the character of Supergirl.
That allows for a total reboot for all characters. A similar approach was taken when developing the new Hawaii 50 compared to the original Hawaii 5-o decades ago.
James Olson as compared to Jimmy Olsen might as well be a totally different character and he is. Making him a black character as compared to the white, young cub reporter Jimmy Olsen is totally appropriate. And actually cool.1
