The reason this show was cancelled:
This show was cancelled because it was a threat to the established order when it was aired. The writers we wonderfully creative people who snuck by a concept that was inoffensive enough to be missed by the thought police.
In 1981, if people started to question why we still used fossil fuels, money, and animals as food, they would be questioning the material basis of their reality and would soon question why we allow a small group of moral degenerates to rule us and control the resources of the planet as if they were ordained by God to do so. (Hint: they are not.)
If the show were remade today, the privileged class would be safe because the quest for alternative energy is now recognized as being a money-maker for the established order and the concept of money is mid-way through the change to an all-electronic form, which will make the illusion of money's value even easier for our puppet masters to control.
Bennu would not look so much like an ancient astronaut hero now as he would a class-conscious environmental extremist, a terrorist. He would be the bad guy.
Love is like breathing. You have to take some in and let it out to live.
