A good space show can be done cheap. Whether people want to watch it depends on it's aesthetic. I don't think people care how cheap or retro fifties it looks. It's all a giant conceit anyway. No bumpy headed aliens. Too many aliens to begin with and too much money poured into too many cooks in bed with each other's pockets. TOS was streamlined and spartan and minimalistic. It's a tightwire minefield no doubt from both sides which is why it should be taken out of CBS hands and given to either NBC, Netflix or and internet web series pay per view, direct to dvd sort of thing.
