Look, I know that Buck Rogers in the 25th Century: The Complete Epic Series looks like somebody vomited up a fashion disaster and everything, but consider that the only viable alternative SF universe to live in (Star Trek) was getting hammered by Alien Space Bats a LOT more often. Besides, after the first series all the danger was happening to people FAR AWAY from Earth. Which is great, if you’re planning to move and everything.
Also, I could be a consultant. As the first link notes, those people were so starved for culture that disco looked good to them.
