I don’t know if a contemporary audience would accept a story about the moon getting blown out of Earth’s orbit. I enjoyed it as a kid. I think adults would roll their eyes at the scientific silliness. As a child the aesthetics captured my imagination. It was like going to museum and starring at a moving picture. The show looked like contemporary spacecraft of the time, not like Star Trek. Again, would contemporary audiences go for that? Many people found season 1 dull ( I still watch it ). I would want the same aesthetic and tone as season 1. I don’t think they could replace Barry Morse, but they certainly can do a better casting job for Barba Bain’s role. I still watch Space 1999 and think how wooden her acting is.
