Discovery does an episode that is a sequel to both “An Obol for Charon” two weeks ago and the Short Treks episode “The Brightest Star,” as Saru proves that you can go home again, and you can completely up-end your whole civilization when you do! My take on “The Sound of Thunder.”
One of the biggest issues I’ve had with rigid “we must not interfere at all!” Prime Directive stories—the worst offenders being TNG’s “Who Watches the Watchers?” and “Homeward” and Enterprise’s “Dear Doctor”—is that they tend to turn the main characters into uncaring bastards when they’re supposed to be heroes. Heroes should never allow people to die when they can be saved. And many of them—”Dear Doctor” being a particular offender—tend to view evolution as this rigid straight line of inevitability that the Prime Directive keeps Starfleet from interfering with. But that’s not how evolution works. It’s not a straight line, it’s a jagged, curved, random, ridiculous line being navigated by a drunk driver. Evolution is constantly shifting, and it’s affected by dozens of external factors.
