Bashir and Kira accidentally end up in the mirror universe, which makes it's first return since it's debut in 1967. It is awesome to return to this classic aspect of the franchise, and it is fun as hell. Nana Visitor as the Kira counterpart, the Intendant, is really fun to watch.
All in all it is good that this universe ripe for good storytelling finally got revisited in DS9, and lead to a sort of mini-arc within this series, there are several other episodes that expand on the story started here.
