Back during the runs of "Star Trek: Deep Space 9" and "Star Trek: Voyager", the "Mirror, Mirror" plot from the original "Star Trek" was resurrected again and again. While I loved the original "Mirror, Mirror", the great evil parallel universe idea was bled dry--with way too many revisitations of the idea. Fortunately, this idea was only used in this and the following episode...plus the style and look of these shows is amazing. What do I mean by this? The normal, wimpy intro to "Star Trek: Enterprise" has instead been replaced with a militaristic intro--complete with the symbol of the evil parallel Federation!
When the show begins, the Zefram Cochran first contact scene from "Star Trek: First Contact" is shown and things seem just fine. However, this has been re-edited--and you realize it when Cochran (James Cromwell) opens fire--killing the Vulcan visitors!!
The scene now cuts to the evil Enterprise--complete with most of the same crew from "Star Trek: Enterprise". But, like in "Mirror, Mirror", these folks are evil, conniving and rotten. How rotten??!! See the show and see for yourself!!
The show that follows involves Commander Archer taking control of the ship from his captain! And, he then sets the ship on a secret mission into Tholian space. Why? What's all this about anyway?!
This is a mega-cool episode. Sadly, however, it's also one that was filmed AFTER the crew learned that the show was being canceled. Clearly a case of too little too late and this marks one of the better shows...yet only a few episodes later, the series sadly ended.
