***** (5 stars out of 5)
First of all, that's a staggeringly fantastic opening sequence. Trek Nerds recognize the end of Star Trek First Contact where Zefram greets Solkar... only instead of the Dawn of Maturity and Peace, psycho Cochrane shotguns the space elf down and steals all his stuff! (Keep in mind, in this dimension, Dexter is a sitcom.)
We discover Reed and Phlox invented the Agony Booth, and, curiously, that the ISS Enterprise crew is already more racially integrated than its counterpart in the positive universe: Andorians, Tellarites, even Orions. Of course, they're all conquered vassals, but still... get to the Tholians!
It's not just another evil parallel universe story, but a sequel to 'The Tholian Web', in which those dastardly crystal lobsters have got their claws on a tasty piece of future tech in flamboyant 2260's style... U.S.S. Defiant.
Mirror Archer proves he's not as unambitious as his Captain Forrest thought, torturing and blasting his way onto the bridge of the most powerful ship in the universe. Who wants the first orbital barrage?
"In a Mirror, Darkly" has lots of twisted amusements: Doktor Phlox dissecting his menagerie, Ho-shi trading up from Forrest's bed-warmer to Archer's, and Big Dick Tucker looking like he took a nap on a hot plate, but they had me at the revised opening credits. Earth thugs killing everything they see until they conquer the moon! Humans are the WORST... but you kind of have to admire their can-do spirit!
