Sometimes there was an honest effort. When Trek got popular inthe 70's, a few network shows tried to emulate the format, and writers like DC Fontana, David Gerrold and even Harlan Ellison were hired to pen some good SF. Logan's Run was a nice try, but their scripts were watered down by the producers or the network. The Fantastic Journey was also another good shot at quality SF. But budgets seemed even smaller in the 70's (even at it's cheapest, Trek didn't look as crude as Logan's Run). However, once Star Wars appeared, intelligence went right back out the window and Glen Larson took over. It works as a fantasy, if not sci-fi. And I still hold to the opinion that Twilight Zone was primarily a fantasy series with sci-fi episodes in the mix. It was still a "magical stuff happens" series. So you know, I am not disagreeing with you at all. I was just saying the list of choices for American sci-fi in general was longer than you suggested. But I'm with ya.
