You will find his essay here, and I have many points of agreement with him, but I think he undervalues the first series. Characters and script were excellent in about sixty percent of the original episodes. It is also noteworthy that the original characters have entered popular culture for an enduring period of time and we are still making movies about them forty-five years later. It’s not absurd to think of someone saying “Beam me up, Scotty” fifty years from now. I don’t see Data or any other later character receiving the same treatment, nor do I think that any of the later installments would have, on their own, generated an entire franchise of installments, spin-offs, sequels, and the like, where Matt can tweet something like “Animated series is non-canon, people. Get with the program.” If you’d like a treat, watch some of the D.C. Fontana-scripted Star Trek episodes, noting that “Tomorrow is Yesterday” is one of the funniest and most profound takes on “the great stagnation” to be found in popular culture or anywhere else for that matter. And it was written before the great stagnation even started, and by Roddenberry’s office assistant at that. Magic was in the air. As for “Spock’s Brain,” well, that is another matter.
