Ds9 trek was best trek even when they had the wheel of morality out for an episode or two.
The worst episode was where Rom organized a union and quoted the Communist Manifesto to Quark. I did like Quark’s betrayed, “What happened to you?”
Other than that, great series and Sisko was the best post-Kirk captain. I was surprised upon rewatching Voyager that Janeway had some brass and wasn’t as PC as I remembered.
I may have been a bit harsh of DS9, but by then I was beginning to suffer Trek Fatigue... However, the episode Past Tense was the worst of all Star Trek shows.
