Like many early Sci Fi tv shows, the ideas were there but budgets, scientific knowledge, and production capabilities weren’t.
Buck Rogers was talked about being restarted a few years back. Erin Gray at the last DragonCon I went to then, said it was being pitched around but that’s the last I heard.
Space 1999 got a demo called Space 2099 with a ton of digital rework made it a lot more futuristic and sensible.
I would love to see a Buck Rogers remake—however, call me crazy, but I would love to see it done like the early comic strips where it’s more steam-punk and they were fighting Chinese warlords with advanced technology, but we know that’ll never happen now.
