A very standard and predictable story about bickering rivals getting stranded together actually turns out to be quite good fun thanks to the great chemistry between Odo and Quark, and the actors who play them. The mountain scenery makes a nice change and we get to see Odo experience how frail a human body can be now that he doesn't have his shape shifting abilities.
The arguments between them do get over-the-top. Odo has had numerous chances in the past to "catch" Quark in a crime, so it feels a bit odd that this is the time he finally decides to do it. And of course, we know that the two of them don't really hate each other at all, although calling what they have a "friendship" does feel like a bit of a stretch. The closing moment of the episode encapsulates this nicely.
In some ways the b-story with Jake and Nog is even more fun as it rips off The Odd Couple. The show always managed to make Jake's relationships with both friends and family feel natural and it's easy to get invested with them. Sisko does a pretty great job at sorting their problems out, and I quite liked that his solution was a simple as "deal with it!".
Nothing special overall, but quite an easy watch.
