I dislike animated series, outside of animated comedy, & prefer live actors. Because of the awesome ‘Center Seat’ documentary (only thing I disliked was <I think was last 2-episodes> auction coverage, because just wealthy enough people to store away ‘Star Trek’; instead of just COOP & thus, accessible by all Museums) about ‘Star Trek’ universe’s from very beginning to the release year of the documentary, I know the only serious & mainstream award awarded (I think it was a Emmy) to any ‘Star Trek’ series has ever won, was this series for one of their episodes. I have yet to watch the Emmy winning episode, but still the stories are good to The Original ‘Twilight Zone’ already did that.
I am keep watching the series,
The reason why you aren’t finding it on the main Emmy site archive is because in the 1970s children’s programming was grouped with the ‘Daytime Emmy’ awards regardless of when a show was broadcast.
