I'm now just over half way through DS9 series 3. So, given that it's 7 seasons long, I'm just over half way through DS9. And so far it's very patchy. It has some of the worst episodes of Star Trek I've ever seen (Fascination, for example). And the very worst acting. (Sisko). I'm not getting the "it's the best series" vibe at all. And as for the reputation it has for doing "politics" well; the time travel to the Earth ghetto was overtly political, but while a fun romp, was hardly quality political insight. It was cringey at best.
