The μniverse has had a sad journey on DS9. It started out as a genuinely twisted and sinister take on DS9, with characters that served as an interesting parallel to those in the prime universe. But it soon became a place to have comic-book adventures without fear of serious repercussions, and the attempt to salvage the concept into something meaningful in Resurrection resulted in a somewhat dull distraction to DS9's more interesting storylines. Now the μniverse must suffer the ultimate indignity, relegated to being the setting for a Ferengi comedy episode. What an inglorious way to go.
That's the best analysis of the MU I have ever read. I actually never made it all the way through this episode, as soon as Vic appeared I was done.
