Watching Deep Space Nine right now, just finished S1. Pretty forgettable story wise but I did enjoy the last two episodes. Great cast with great characters. Didn’t realise Baltar from BSG was in this, great actor.
One thing Star Trek does very well is the “alien” species all being distinct from one another in terms of culture and ideology - the Cardassian characters are pretty great for example, even if they are basically just fascists.
It was actually Dukat in that scene, although Garak was also a great character. DS9 had about a dozen great characters and almost no uninteresting ones (Jax was a bit shit) which carried the show as the plot was very thin for the 7 seasons and only gets going on s6.
