Yeah, some of the Fx stand the test of time don't they? Shocking given that this was made in the early 60s. And because it was made in the early 60s it certainly has the most moralistic bent to it, and for a series like The Twilight Zone, it works and it sets it apart from all the revivals made to date. Sure, yeah, the 2019 has a "moralistic" side as well, certainly more than the 80s and 00s revivals, but the 2019 morals are more... propagandist, more hateful. This version, the morals are about individual virtue, about loyalty and courage and wisdom and not about... well, not about partisan politics and division. That makes a difference in the story telling. You have lessons, like don't become reliant on superstitions that you really hardly see in the 00s and the 2019 revivals, and you only occasionally saw in the 80s revival. You have episodes that have a warning, a clear cut warning that serve as a guideline. And then you have your pure science fiction episodes that, even then, come with a love of pure irony that made the series so well loved. The twists and turns are spooky and heartwarming. What's not to love?
