I do wonder how many people in this thread actually watched the original Battlestar Galactica or even Buck Rogers when they aired originally. I certainly did. Coming off Star Wars mania, it was a pretty big TV event at the time. Ships and effects from people who worked on Star Wars too.
Expensive show but impressive as hell for TV. My child mind exploded, I was so there for Muppit (if you know, you know). Pretty legendary TV show, the toys were good too. Even the concept of Earth and finding it, then protecting it. Was pretty great. The new series failed to land the ending after 2-3 seasons of such promise.
Galactica 80, really did some damage to the overall status of show. Even though as a kid, the flying bikes, cloaked ships and kids with abilities due to different gravity was all the rage.
In terms of movie to TV series, I much rathered preferred Terminator Sara Connor chronicles to Star Gate. Even V was much more impactful overall.
