Well I wasn’t ever a big fan of DS9 (though I liked it far more than Voyager), so I really don’t remember much about it. I didn’t really care for the first officer very much, and the trill (Dax?) didn’t really strike me as a “strong” character. But I understand there was a lot more character development in DS9 than the other series, so perhaps I misjudge based on early episodes (If TNG were judged on its first season it certainly wouldn’t fare well).
