I'm trying to tell him such a abomination like Galactica 1980 per definition can't exist, but yet he insists there is something like that. Someone made it up to scare Sci-fi fans all over the world, and damn it works. It's the '80s TV version of a Rick-Roll.
If there where such a show, and we all know there isn't one, no one would like it, no one would like to hear about it.
There was a attempt to make a second season of TOS Galactica, but only two members of the original cast where available, Dirk Benedict ( Starbuck ) and a Cylon Centurion. The attempt failed, the show was cancelled after one episode, end of story.
