There are 5-6 crap episodes in every season of DS9, and more than that in Season 1 in particular.
You won't get an accurate list from posters on this or any site though, or any review site, because everyone is biased to their own tastes and likes/dislikes different things (although there are a few really bad DS9 episodes that are almost universally disagreed upon as being really bad, but even those have fans who enjoyed them...). In fact, I already see many good-to-great episodes of DS9 being recommended for you to skip in this thread.
The only way to really know which episodes you find bad is to slug it out and watch them all. Otherwise, you might miss some great episodes because some posters here told you to skip them since they were bad to their tastes, but not necessarily because the episode itself was inherently bad.
