It would be ok if they left race out of the movie, but you know what ever studio is going to lay some stereotypes on him or "urbanize" him. If they made a black superman, like a naive farmboy from Kansas, that would be ok imho.
Hollywood tends to stereotype blacks into certain parts. There needs to be more educated films that have black leads like "The Brothers", "The Best Man", "Two Can Play that Game" and "Brown Sugar" and less of the stereotypical garbage that they are producing now....not that I'm complaining about "I'm Gonna Git You Sucka" "Don't Be a Menace to South Central ..." or "Harlem Nights", but I'd like to see more diversity
