This is an exact reason to blame the suits. They had Star Trek which was a license to print money, and they just discarded it. If a show is good, it should find an audience.
Bring back “BJ and the Bear”!!!
But Star Trek wasn’t a license to print money at the beginning. When it started it was an expensive show with crappy ratings, 40 years ago nobody knew Star Trek would find it’s audience 5 years after it got canceled. It’s nice to say that a show “should” find rating, but when you’re the guy writing 6 and 7 digit checks every week to keep a show on the air “should” doesn’t cut it, you need a show to have already found it’s audience. And it’s even more true today than it was before, the pie is cut thinner than ever, most of the networks (especially NBC) don’t have the big hit shows making enough money to keep a couple of experiments around. They need every episode of every show to be profitable, they no longer live in a world of letting Cosby make enough money to keep Cheers around and see if it catches.
