The whole push for mirror universe episodes happened way too early in the shows timeline IMHO. The focus on the MU concept and the neato factor rather than the characters and their interactions and relationships with others, I think, is a mistake. A mirror universe would have served the franchise better if introduced in the second or third season, after the characters and relationships have been established / explored.I think the idea that everything is "backwards" in an alternate universe is a bit overplayed. I like it better when it creates twists in characters, not always polar opposites.
Maybe in such a brutal empire, its more neutral because it's pretty merit based.
If you can kill better, you're higher up. And maybe some women are just better at killin'
