Conscience had 1 act that worked, and 3 that didn't. Kirk searching for the truth and putting the pieces together are the only part of the episode that's any good. The plot about a former genocidal governor is a great premise. My only problem with the play at the beginning is that you can't tell the difference between normal 60's Star Trek sets and play props. The ending though, that ending well and truly earns it a spot at the bottom. This one was on many people's "worst of Trek" lists, and with good reason. For a show that brought so many races together that weren't typically seen on television in the 60's they sure love taking shots at women! In particular the "hysterical" crazy woman archetype that gets reused throughout the series. As for Alternative Factor. Even if you put aside the worst VFX in ALL of Star Trek history, the plot(if you can call it that) is a disjointed mess! Again, let's even put aside that they pulled the actor onto the set with no prep time, and the plot still doesn't make any sense! But hey, everyone enjoys different Trek. I would love to hear from you folks that keep saying these are good episodes, what's worse than them? Even if you consider that ALL Trek is good Trek, there's still 1 that's 754 better than another!
