Enterprise is hit with a powerful "non-existence" distortion. It seems to have emanated from a strange spacecraft alone on a barren planet... but the ship's lone occupant, Lazarus, is oddly evasive about what he knows. And is he the ship's lone occupant? It seems a twin Lazarus from an anti-matter universe is periodically trading places with his double, while at other times the two become locked in personal combat. Will their conflict destroy the galaxy?
If you can somehow put yourself in a 60-year-old mindset, remembering that this was Star Trek's first "alternate universe" episode, you can perhaps appreciate the fact that a science fiction show from the 1960s was taking on such a bold, complicated story. But that's pretty much where my appreciation for this episode ends.
The story's ambitions far exceed the production's grasp. The alternate universe is represented in overly literal fashion, in "photo negative" footage shot on an empty, smoky sound stage. The location filming is back at the Vasquez Rocks yet again, and making no effort to hide the familiar formations that were already featured in earlier episodes. Lazarus' spaceship is a Jetsons-style flying saucer, and his beard looks too fake even for a Spirit Halloween costume.
The pacing is glacially slow. Characters stop by the mess hall for a coffee break in the middle of a red alert. They make dumb decisions to prolong the "mystery": again and again, no guards are put on Lazarus or his ship, even though our heroes say they don't trust him. And yet it's clear that even as slow as things are, some scenes have been trimmed for run time. (People know Lazarus' name before he tells anyone.)
When it's finally time to unravel the mystery, the leaps in logic have even less foundation than the earlier lack of suspicion. If one Lazarus was "good" the whole time, why did he never share any information? We're told that the two Lazaruses meeting physically would annihilate both universes... despite the fact that we've seen the two of them physically grappling with each other again and again throughout the episode. And why does Kirk tell two security guards to just stand back, leaving them to stupidly watch Kirk try to physically restrain Lazarus?
The ultimate resolution is meant to be poignant: "good" Lazarus is making the ultimate sacrifice to be locked in conflict with his doppelganger for all eternity. But why is this the answer, as opposed to consigning each each version to his own reality? Why can neither kill the other while they're in this liminal corridor between realities?
Why do we get this engineer "Masters" in this episode instead of our beloved Scotty? And why does Masters get a first name when neither Sulu nor Uhura got one for the entire run of the original series?
I just don't find much to like here. I give "The Alternative Factor" a D-. It's clearly the worst episode of Star Trek's first season.
