I still am trying to figure outwhen this became a measurement of quality. Entertainment, by it's definition, is a sensory, temporary thing. That TOS and TNG have some staying power is as much about the times they were made in as the quality. So what if a story isn't remembered 50 years from now. Did you enjoy it now?Not sure it'll be much remembered in 50 years.
Yes or no?
No? Then move on.
