I remember watching Quark when it was first on. There's no way a show like that would have a chance today. But at the time there was practically nothing on TV in the way of sci-fi and after the success of Star Wars stations were scrambling to find any sci-fi they could air. The demand was also responsible for Battlestar Galactica and the popularity of anime in NA.
I liked Man from Atlantis. I think the problem with the series is that they relied too much on one villain for the start of the series. The later episodes had more variety and more experimental sci-fi stories, but by that time it was too late.
I never watched Lucan nor was even aware of it.
The Logan's Run TV series really had nothing to do with the movie, although I liked it.
It's interesting that many of these shows are the same sort of stories that appear in many children's live-action shows. But during the 70s there just wasn't anything for kids other than the Saturday morning stuff. And everyone in the house watched the same TV. Prime time shows tended to be more family friendly.
No show about airlines has ever been a success. LAX lasted only a single season and it appears this season's Pan AM will have only 14 episodes.
I thought I saw Supertrain but what I recall was Time Express which had a Fantasy Island premise. It didn't last more than four episodes but it did star Vincent Price. It definitely beats Supertrain for obscurity.
