Hi Bijou88,
I agree, most of the time it was fine. Just the occasional over-the-top dates it badly. If it were more like 2001 a Space Odyssey, using classical music, it would work much better and hold up more, IMHO. Still, I love the show, and even though it sounds like I'm ragging on the music, it was only like twice it happened to really bother me. Most of the time, it was fine. I love the two main themes.
Space 1999 has a unique feel and some fantastic stories.
