Season 1 of DS9 was easily it's weakest one much like TNG. It took them some time to find their own unique niche with the space station show vs the ship one, and it didn't help that they brought just about every extra from TNG over at some point in season 1.
Season 2 isn't going to do anything breathtaking(until the end of it anyways), but the episode quality is drastically better. Season 2 will introduce the Maquis to the Trek universe(ironic that DS9 ended up using them more, when they were supposed to be just setting the backstory for Voyager), plus one of the huge villains of all Trekdom.
By the time season 3 rolls around you should be hooked though as that's where DS9 starts to become great.
