So I just finished watching "The Alternative Factor" on Netflix, remembering that I'd never met a fellow TOS fan who liked it. Yet, when I watched it as a kid, I actually enjoyed it. Now, at age 31, I still don't understand the hate for this particular episode. It has a decent storyline. It has the perfect resolution (making the anti-matter universe Lazarus into an ultimate heroic figure by his self-sacrifice). It seems to me that there are plenty of episodes from Season 3 that are far worse, so what gives?
Beyond the lame special effects for the two Lazarus jumping from universe to universe, as well as actor Robert Brown's ability to out-ham William Shatner, exactly what makes this a bad episode in your opinion?
