I <3 DS9 so much. I did a re-watch a few years back of the entire series and loved it. There are eps that aren't as important to the main plot/sub-plots but some of them are just fun and good. Also, you don't want to skip any eps when you get to the Dominion war, all those eps from that point on (even the few that are stand-alones) are really great. Kira is still to this day, one of my all time favorite characters :)
