||I'm sure someone, I think Jammer on his review site, called Tuvok's appearance in this episode "gratuitious". By this I assume he meant a pointless exercise in having a Voyager crossover, since Tuvok contributes nothing at all to this episode, he just stands there looking over people's shoulders while they all argue. Surely if you're having a crossover, you'd give the character some vital role to play. He's also no different from the Tuvok of Voyager - it seems that Vulcans are the same in any universe (we see this in ENT, TOS and now DS9; shame they didn't make the mirror Vulcans interesting, perhaps by showing them as slaves to their violent impulses). The actress playing Jennifer Sisko puts in a dreadful, passionless performance, but nearly everyone else is very good (if visibly over-acting on occasion). Mirror Kira and Mirror garak are basically this episode's saving grace, but you definitely aren't getting the best of DS9 in this episode. I mean, look at the humans in TOS and ENT mirror episodes, then imagine them being portrayed as victims fighting a heroic war against persecution. I'd say the mirror humans are bad enough in TOS and ENT to deserve everything they get in DS9.
