"The Alternative Factor" (TOS) - yes it has some flaws, but I don't think it's as bad as some make it out to be.
"Genesis" (TNG) - this was always one of my favorite TNG episodes. Pretty freaky! Although it premiered in March, it could easily have been the TNG Halloween episode.
"Threshold" (VOY) - I can easily see why this one is generally not a fan favorite, but I like how they explore the limits of warp travel as well as Tom's obsession with the project despite what's happening to him.
