Again, I never said it has anything to do with quality. Clearly DS9 was made with same level of care and craftsmanship as TNG, some could even argue that it surpasses it. What I said was that it simply didn't interest some of the audience of TNG. It was given a fair shake. The ratings for the DS9 pilot were massive. A whole bunch of people gave it a shot, and then a portion of them said "no thanks." It doesn't mean they were unable to comprehend deep dark characters or whatever elitist sentiment gets tossed around. They weren't into it. I am. That doesn't mean I'm able to see something they don't, it just means I like what I see and they don't.
Ok, I agree with that. But I don't think it's fair to characterize people's defense of DS9 as saying it's more 'Deep' and too hard for people to understand. And, you did
earlier say that you thought the reason for TNG's greater popularity is greater quality.
But you're right about the basic reason for the lower ratings. DS9 doesn't entertain the same number of people TNG does. It's not a matter of most people not being able to comprehend it's 'depth' or anything like that. DS9 and TNG are equally 'deep' in different directions. It's a matter of there just being a greater number of people entertained by something light and fun than something dark and critical of human nature.
But, I do think that a lot of people who might have liked it dismissed it too early because it wasn't TNG redux. Because it didn't say 'Humans will evolve past all through their current problems', it said 'Human failings are permanent'. And I'm saying that because it's exactly what I did when the show first aired.
