A Parallel Universe of Tyranny and Betrayal
1 May 2010 | by See all my reviews

On 5 April 2063, in Bozeman, Montana of a parallel universe, Zephram Cochrane kills the Vulcans in their first contact. On 13 May 2155, the humans are part of a dark Empire that uses force and torture to subdue other species and they are near to be defeated by the rebels. In Enterprise, the First Officer Archer leads a mutiny against Captain Forrest and travels to the Tholian space to take the Earth ship Defiant that has come from the future of another universe and has been captured by the Tholians that intend to use reverse engineering to research the advanced technology and weapons. In an environment of betrayal and mistrust, Captain Forrest and most of the complement of Enterprise are destroyed in an attack of several Tholian ships. Archer, T'Pol, Trip and a small group try to activate the Defiant to battle against the enemy ships.

"In a Mirror, Darkly: Part I" is a weird episode of Enterprise in a parallel universe where tyranny and betrayal rule. The characters have basically the opposite behavior of the regular ones and Hoshi surprises with a sexy performance that seems to be inspired in Mata Hari. The best part of this show is the excellent music score that replaces the annoying and out of context theme of Enterprise. My vote is six.
