Great premise only DS9 can do, executed wonderfully. Fun to see these three TOS Klingons again as a trio of bickering old bitches, and I like that they're all basically supportive of Dax's transition. :)
The story could've stood to hang the final decision on the conflict a little more on Dax, maybe, instead of keeping her quite so clean, but this is still a great hour of DS9.
