Something my Art & Literature teacher is CONSTANTLY drilling into me is to look at art in context. TOS is "campy" and "sexist" because the writers saw a very real wrong in the world and that it was being filmed during the Sexual Revolution.
TNG is wimpy because it is swinging towards the opposite of the current generation, the ME generation.
DS9 I can't comment on, because I couldn't stomach to watch it.
Voyager was, in my eyes, pure magic. Something that looked at the world through unfiltered eyes.
Enterprise is making the fatal mistake of posing for the crowd. I've still got my Star Trek: Judgement Rights Collector's Edition with the interview of Gene Roddenberry, and he said the highest mistake any writer can make is to prostitute himself to the audiance. Once the writer's get their guts back and get Archer out of Xindi-land, it will be as good as it was before.
Many things from times gone by look strange, weird or wicked. Certainly Alice in Wonderland can be very disturbing if you read it right. The historical context is that children's reading material at the time before that was preacy, superior, poorly written, and dry. It was, in essence, a child observing an adult's world and trying to make sense of it.
You could easily make a case for "Wonderland" to being adulthood.
Once again, you have to look at in historical context.
P.S. I realize that, in a post spouting emotional absense the praise of Voyager and the condemnation of DS9 does not fit, and I apologize.
