I'll start by saying it is a nice change from the constant problems of starships. To make the setting a ramshackle space station that has been decimated by its previous tenants, makes for a new dynamic. We are also informed of a race of people, the Bejorans, whose population is living in poverty and despair, waiting for their religious leader to gain some sort of stability and avoid a civil war. The space station has a Bejoran woman running the show and a shape shifter, Odo, who is a constable. There are so many others and so many plot lines set up that it would be silly to try to mention them all. Mostly, the hero is a man who is putting his life together after losing his wife to a Borg attack. He starts out with a huge weight, unhappy at the assignment to get DS9 back in line. I appears to be quite promising. I saw a few episodes when it came out, but missed any continuity.
