I think I would have been annoyed at the black characters in LOTR 20 years ago. I also would be annoyed at a black James Bond. The character as written by Ian Flemming is a Scottish dude who is rough around the edges and so forth. As much as I think Idris Elba is a great actor, that isn't James Bond. But, neither was Roger Moore. But, I'm thinking people who have a problem with black hobbits and black elves...are some racists.
