This is the second part of a wonderful two-parter. While I loved the original "Mirror, Mirror" episode from the old "Star Trek", this evil parallel universe was way, way overused in some of the subsequent Trek spin-offs. At first I liked it when the crew of Deep Space 9 was visited by these evil parallel doubles but after so many follow-ups, it became way overused. What I loved about "Mirror, Mirror" was its originality. Fortunately, in "Star Trek: Enterprise", they managed to use the old concept but infuse it with wonderful originality and life. I think this two-parter is in the must see category for fans.
In the previous episode, Archer orchestrated a mutiny in order to try to steal a ship that was somehow stolen from the future. With it, he planned on taking over the evil empire and being its evil emperor. However, in part two, there were some hiccups, including a Gorn aboard the stolen ship that was trying to disable the vessel as well as the machinations of the evil and often disloyal crew. Can Archer manage to rule this awful parallel universe?!
This episode has so much going for it. Like part one, the normal intro for the show is replaced by an evil intro--complete with martial music and clips of war and violence! It also did NOT feature nice beings from our universe--just very, very bad ones from theirs. It was NOT like the nice Trekkie folks getting stuck there but as if it was a show intended for an evil audience to enjoy! It also featured a deliciously evil ending--with no redemption, no nice ending and just more of the awfulness that make this parallel world fun to watch. My only complaint is a minor one--why make a CGI Gorn when the CGI quality was that poor and obviously fake? I really think the original "Star Trek" Gorn looked better!!
