From the moment it opens, with the scene from Star Trek: First Contact and the music. And then the Vulcans step off the ship, the guy salutes, and Zefram Cochrane pulls out a gun and shoots him-- then the group races forward and raids the Vulcan ship. End scene and then the epic opening begins-- the dark [i]Star Trek: Enterprise[/b] and the epic, evil music. Followed by approximately forty minutes of pure awesomeness. From what I know of the other mirror universe episodes in the other Star Trek series, they were about people from our universe, crossing over into the mirror, but it looks like this one is all about the mirror universe.
