Of all the finales I watched, I would have to say the Star Trek: Enterprise Finale was the best. The official Star Trek synopsis is:
Aboard Degra’s ship, Archer, Reed and Hoshi work with the Arboreals and Humanoids to chase the Reptilians and stop the Xindi Weapon from decimating Earth. Archer’s plan is to board the weapon and try to overload the power systems, but he’ll need the help of an ailing Hoshi to read the weapon schematics.
Back in the Delphic Expanse, T’Pol leads the NX-01 in an attempt to obliterate Sphere 41 in hopes of disabling the entire network of Spheres. But the crew’s time is limited, as that region of space has a degenerative effect on their bodies, and the furious Sphere-Builders try to tear Enterprise apart.
What they don’t say what happens in the last 15/20 minutes. Archer, with some help from the Andorians (one of them played by Star Trek veteran Jeffery Combs) suceeds in destroying the Xindi Weapon. However, Archer is killed in the blast. It seems as if Paramount has rewritten the rules for what people are okay and not okay to kill off. Anyways, T’Pol and Trip just barely destroy Sphere 41, and not before the Sphere-Builders manage to get on board the ship and cause some chaos.
In recap, Xindi Weapon: Destroyed; Archer: Dead; Sphere’s: Destroyed. The only thing left is to go home. So the NX-01 heads to Sector 001, Earth, Sol System. They arrive and find things are not the way they left them. Earth doesn’t respond to any of their hails. Reed and Mayweather head down in a shuttle pod and they’re attacked by what looked like….P51 Mustang. Yes, that’s right. World War II propeller planes. Of course Paramount isn’t stupid, so what’s become of Archer. He just suffered some burns and is resting in a M*A*S*H unit…a Nazi M*A*S*H unit!! So now I’m like, “Alright, they went back in time or something when they went through the vortex.” Well, I don’t think aliens were fighting hand and hand with the Nazi’s.
So yea…Star Trek: Enterprise definatly wins two prizes. One for Best Season Finale and one for Best Television Comeback. Go Enterprise; whooot, whooot!
