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?
Imo, the best place to jump in if you refuse to watch all the episodes is S1 E1-2 (the opening episode for the series) then immediately skip to S2 Last Episode of the Season. That's where the main story-arc of the entire series begins. Unfortunately, I think some of the next Season 3 episodes might be a little dry but they're still better than some of the worst episodes of Season 1 and 2.
I'm in the works of rewatching DS9. I'm into season 3 now and so far there's only been maybe 1-3 terrible episodes I had to skip through.
I would caution you away from skipping too much. Part of what makes the characters so good in DS9 is their character development and understanding the historic basis for some of their actions. If you skip too much, you'll lose a lot of the subtlety of the character interactions which is arguably the best part of the series. On a higher level, it's as if the whole space station is a bunch of misfits with completely different agendas that in the beginning causes conflict and misunderstanding but as time goes on, they find common ground to work together in their own way. Seeing that develop is worthwhile, imo and that's where a lot of S1-2 comes into play.
