Haven’t read the comments yet, but it seems to me this author’s idea of a bad episode is any one that entertains any notion that isn’t PC liberalism.
And the worst STOS episode was The Empath, with Mark of Gideon a close runner up, neither of which is mentioned.

I agree with the “TNG” assessments (although I don’t remember the African tribe one), but they missed two key awful, awful episodes: “Force of Nature” and “The Game.”
“Force of Nature” is the infamous “hole in the ozone layer” enviro-whackjob episode. At the end, Starfleet implements a Warp 5 speed limit for the Fleet. Naturally, since that’s quite an inconvenient truth (har!) the directive’s impact and limitations are never mentioned again in any episode or film.
“The Game” is a Wesley episode, so that’s strike one, two, and three. It has a young Ashley Judd. It has a terrible premise. It has a brutally stupid conclusion. Other than that, it’s great.
Any and every Voyager episode or any with Janeway in it
