Says it all.
Says a lot, at least. Of course, fans of the show and its positive vision of the future have been derided for the past 35 years. Given the national mood today, I would expect that to increase.
Harlan Ellison (a brilliant writer who seems perpetually pissed off - possibly it's the crux of his creativity) said that after Desilu Productions and NBC were finished with his teleplay, it resembled a "thalidomide baby."
But the gist of it came through. Kirk, having been transported to early 1930's Earth, falls in love with a woman (played by Joan Collins, when she could still inspire palpitations.) But he and Spock are there to find a drug-crazed McCoy, who, it is found, had profoundly changed world history by saving the life of Kirk's new-found love.
Had she not been run over in the street, she would have founded a pacifist movement, delaying U.S. entry into WWII until Hitler had the Bomb and a delivery system. HE WASN'T STOPPED SOON ENOUGH and the world paid a terrible price that rippled into the 23rd Century. Spaceflight never developed.
Today, the parallel is obvious. There is no "soon enough." There is only "now," and the hope that it's not too late.
Go, Mr. President, go.
