I liked DS9 except for the Ferengi. I thought that they took a race that had some serious potential and made them into a campy ridiculous farce and a running gag. Not good.

Obviously this race developed a culture and society substantially different from that of Earth, and yet they come across as bumbling idiots, and the rules of acquisitions? Give me a break.

And I got seriously sick of the "just add a funny nose or badly done ears and you have an alien" approach (Bajorans and Odo).

Other than that the story lines and arcs were quite enjoyable.

I think a series of mini-series about people and races might be extremely interesting.

You know, someone inspired to tell stories along the lines of Vance in the Star Trek universe. We could do a heck of a lot of exploring of new life and new civilizations. Vance did that with one character - in his case a ruler of a section of the galaxy - who kept turning up in unrelated stories as an anonymous observer and benefactor.
