I did think many of the twilight episodes were quite good. In particular the Kick the Can episode and Monsters are due on Maple street. But hands down, IMO, the best Sci Fi TV series was and ever shall be the 1960s episodes of The Outer Limits. And that is not just me. Spielberg and Cronenberg and Steven king have been quoted saying the same thing. Do yourself a favor and search YouTube for The man that was never born - with Martin Landau or the phenomenal Architects of Fear with Robert Culp. That whole 1st season includes The amazing haunting score from Dominic Fronteire. In both of those 2 episodes, the female leads bring a sweet sadness to the thing and bring the Sci Fi down to a very real emotional level. Yes that is what this situation would feel like. They help us feel that. And Sci Fi isn’t just about super scary monsters and crap. There is metaphor to be found in these stories. We can learn from them. And this has been much of my problem of the morphing of stra trek into rock ‘um sock’um starfights between the Klingons and the Federation. I quickly grew tired of that story arc.
The plotline of Architects of fear was “borrowed” in the graphic novel Watchmen. It also gets proposed by various democrats as a way to pass legislation.
