I just read the collected edition of this. The story's pretty good; I like the way it follows up the occupation of Betazed, a thread that was left undeveloped in the show itself. But the art is startlingly poor. Mainly it's the inking, which is sketchy and ugly, but often the composition is poor as well -- for instance, on the page where Odo arrests the Nausicaans, it's hard to tell that they're the Nausicaans because we don't see them clearly until the bottom of the page.
It's weird how often DS9 comics miniseries have problematical art. I recall the Wildstorm ones being pretty rough too.
