But I was pissed off about Samuel L Jackson being Nick Fury. I think it's racist to change the race of a character, at least if the character is well-established, important and popular.

No, its racist to say that every comic book character should only be played by actors of the same race. Skin color doesn't matter, talent does. I think Denzel Washington would be an outstanding Two-Face, but people like you would never get past that he's not the same color as the character from the comics.

And why are they not using the classic character that was important for so long instead of some recent invention?

They did.

And he was terrible. The Ultimate version of Nick Fury is not only black, but is modeled after Jackson. They couldn't have chosen a better candidate.
