I thought Bakula did fine. Mirror Archer really seemed to be a psychotic personality more than simply Evul.
This. The whole point wasn't to show an Evil version of Jonathan Archer, but a pysychotic and completely incompetent one.
^^^I thought Forrest staying on the bridge and "buying you some time" while his crew evacuated was very un-mirrorish and quite noble. Also, it presages George Kirk's sacrifice in ST09.
This doesn't bother me. The point of the Mirror Universe isn't that everyone is "pure evil," just that they're somehow different from their "normal" counterparts and have skewed moral compasses.
In Mirror, Mirror, Spock, while still an a more evil version of Normal Spock, was still an honorable man. Also, the Mirror Halkans were virtually identical to the Normal Halkans.
Even in the DS9 Mirror Universe episodes (which some people - not me - think were ridiculous) the mirror versions could be honorable people. Just look at Mirror O'Brien, or Mirror Rom, or Mirror Brunt. If fact, I think the biggest mistake DS9 made with the Mirror Universe was not showing us Mirror Dukat - a man who was honorable and good in an evil universe while Normal Dukat was an evil man in a normal universe.
And Mirror T'Pol was not evil either. Can Vulcans be evil? Oh yes - P'jem.
