Show me another series that does multiculturalism any better.
Several shows in the 1960s alone matched or surpassed it.
50% of the starring actors in
I Spy were non-white -- that beats
Star Trek's white triumvirate of Kirk, Spock, and McCoy.
Hawaii 5-0 had more non-whites in the rotating supporting cast than
Star Trek, though the two stars were both white.
Julia -- get this -- even starred a black woman in the titular role!
Room 222 and
Mission: Impossible! both featured an African American and women in their ensemble casts.
The Courtship of Eddie's Father had Mrs. Livingston, who was Asian American,
The Green Hornet had Bruce Lee as Kato, and even
Batman more or less got in the game with the lovely Eartha Kitt as the first black Catwoman.
By the 1970s, things got a little better.
Barney Miller, for instance, had a Japanese American, Puerto Rican, African American, and several white Americans, including Jews and Gentiles, all working together. Still, in nearly all cases, including
Star Trek, it was the whites who were in the most prominent roles; perhaps the oddest example was
MASH, which in its entire seemingly endless run never had any minorities in lead roles, even though it took place in Korea! The closest was Lebanese American Jamie Farr in the supporting role as Klinger.
Unfortunately, in the 45 years since
Star Trek, not a whole lot has changed in terms of who the major characters are and what color the actors who play them will be, even as the nation has become increasingly diverse, all a part of the myopia of Hollywood and the assumption that whites somehow lack the evolution to see beyond skin color when choosing what show to watch. All this effort to reboot old TV shows and movies has just made it possible to further maintain the 1940s-style racial and gender imbalance while making the properties also seem contemporary.
