Here is a fun picture with a whole bunch of science fiction favorite characters from the 70s. I never really got into Buck Rogers, the old Battlestar Galactica was pretty cool, but that came out just after Star Wars, so it had some issues. But Space:1999, that was fine stuff. I was always found in front of the TV on Monday nights for that show, I think it came on at 8:00pm right after the Muppets.
