I watched this show during the original run, which was when I was in my early teens. I remember thoroughly enjoying it and thinking it was one of the better shows on television. Years later, as an adult, I would see this late one night. I was suffering from nostalgia and decided to kick back and enjoy it one more time. I couldn't bear to watch it! I realized the acting, scripts, and direction.
Granted, the premise was definitely fresh for its time. It could have worked, and if tuned properly and all the problems fixed, could possibly be brought back today. The networks need to remember that the public as a whole really does not mind having to think while watching a program. Mindless fodder is not going to placate those of us who need mental and intellectual stimulation.
