Both parts of "In a Mirror, Darkly" are entertaining, well paced, and of course it's a joy for Star Trek fans to learn what happened to the "Defiant" from Kirk's era. Most actors are doing a good job at portraying the corrupted, evil counterparts of their characters - especially John Billinglsey (Dr. Phlox), I think. Also, the music is decidedly more interesting than the usual Enterprise fare. However, the whole "evil mirror universe" thing is extremely overdone: In a society that permeated by universal mistrust, treachery and series of usurpations, where any kind of teamwork is overshadowed by force and fear of backstabbing, I can't really envision people being able to get a spaceship into orbit, even less building an empire that lasts for hundreds of years.
