This show had it's problems but in the mid 70s there was very little choice in sci-fi TV. I watched every episode as they aired in the US. Other sci-fi shows at the time were Six Million Dollar Man, Bionic Woman, Wonder Woman and Invisible Man. While they were ok ,(sometimes better than ok) they were all similar structured, main character hero shows. Space 1999 was much more of a hard, space based, multi-character sci-fi show.
