The Alternative Factor

Episode Summary & Review

Summary

An alien named Lazarus is somehow responsible for a kind of “winking out” effect – all of reality seems on the verge of collapse. He is fleeing a monster whose intent is nothing less than the destruction of reality. But through a mishap, Kirk is transported to the home of that monster. And he looks exactly like Lazarus! Kirk must decide which of them – if either – is the monster. If he guesses wrong, it’s the end of everything.

Our Take

A mixed bag: some good moves, some filler. Star Trek: The Original Series running at cruising speed.
