I watched DS9 when it first came out and I was... underwhelmed.
But then I caught a few episodes in syndication, and it seemed pretty good -- the captain shaved his head; there was this guy (Gul Dukat?) who had really interesting conversations; there seemed to be action everywhere.
Is there a season where I can start without all of the boring stuff?
Bald and Beard Sisko is definitely when things ramp up. Can't remember when he changes the look though. Season 2?
