It's not a matter of race, it's a matter of story. I don't care how good an actor is, put him in as Robbie's son or something, maybe set him up as a villain in the future or Eli from the Young Avengers, something like that, but Spider-man is white. Nick Fury had his reasons, the Ultimate universe, but the Kingpin is a fair point. I like the Kingpin in the comics and, while the guy they got is an amazing actor and did the job perfectly, I was confused. Of course, I was probably eight at the time, but still.
Spider-Man is white, living in Queens, saving Manhattan. If you turn him black, people are automatically going to move on to racist plots, especially with Queens and Manhattan. I have no issues with having a black actor play a black character (I'm really hoping a Luke Cage movie gets made), and no problems with Nick Fury since there is a minor justification, but the second they start making changes like this to the movie, I know, KNOW, they'll take other creative liberties with the story and the whole thing's going to sink.
And that's the real fear, Sony shouldn't be allowed to screw with the story any more than they're going to already. That being said, if this guy's a good actor, I do like the idea of casting him as another hero or an upcoming villain. Eli might be Avengers property, but I'm sure they could find someone for Spidey to team up with at some point.
