Re: If TNG/DS9/VOY were never made, would you have watched TOS?
TOS first aired when I was a teenager, so I never perceive what people call the cheesiness factor. But to put that in perspective, I'm usually able to watch the really really old stuff like Fritz Lang's original, black and white, silent film Metropolis
, or Buster Crabbe's old Flash Gordon/Buck Rogers serials and accept them as visions of the future in the context of their times. It's likely thanks to the efforts of early fan-historians like Forrest J. Ackerman that I can appreciate things before my time.
