Why, can I ask?
I have a feeling if it were a first or second season show, it might get a bit more respect.
Not from me. I conceived a dislike for it back in the days when TOS was on semi-permanent rotation in syndication and it was just
an episode of Star Trek. I never really even thought about what season it was from until long after I knew I disliked it.
What do I dislike about it? Almost, though not quite, everything, really. The main reason, I think, is that the plot is chock-full of cliches, and it's also just a sloppy, poorly written mess. I'm sorry but it is. Yet another planet whose evolution is a duplicate of Earth, yet another race that looks 100 percent human (although I think maybe they try to explain that? can't remember - and besides, even if they do, I'm betting that they do so using yet another cliche), yet another beautiful woman who Kirk loves and loses, yet another relic of an advanced civilization that poses a threat to the Enterprise, yet another "primitive" culture protected by that artifact, yet another phony crisis - involving an
asteroid, even - yet another moment when Kirk is saved from sudden death, etc.
I mean, giving the hero amnesia? Please.
And I truly dislike the soppy sentimentalism of the thing. Some women swoon when Kirk gets romantic; me, I want to look away from the TV screen.
And, oh dear God, the dialog. The romantic dialog is horrible, of course, and the pseudo-Indian dialog is even worse. I guess we should feel fortunate that they didn't discuss "wampum" or (as far as I can remember) "peace pipes."
And speaking of pseudo-Indian, I hate it when shows create those generic, let's-pick-and-choose-from-a-smorgasbord-of-separate-and-distinct-cultures-type Indians. Yeah, I know lots of shows were careless about that stuff in the 1960s, but the thing is that since my parents did care about such things, I knew from a very early age - probably even as early as the late 1960s - that Navajos aren't the same as Cherokees which aren't the same as Zunis, etc. So I hate ___(fill in the blank) ____ Indian tribes. A lot.
And speaking yet again of pseudo-Indians, when they don't even bother to use people who look like American Indians, I hate that even more. The actress who played Miramanee was a beautiful girl and (as far as I can remember) a respectable actress, but she looks no more Native American than I do, and I am about as Caucasian as a person can get. Yes, I know shows in those days were careless about that, too, but on a show that did go to quite a bit of trouble to show genuine diversity, it's really not excusable. And a side effect of that, BTW, is a lot of really bad dark wigs.
And I hate it when Kirk (or anybody, really) falls deeply in love...but forgets about his lost love about 27 seconds after the credits roll. In this case, he even forgets about his
lost child, for goodness' sake. Hate that, hate hate hate.
What I like about the episode is the scenery. It was nice to see them shooting outdoors instead of on a sound stage. Hmmm...that might be it. I haven't - for obvious reasons
- seen the episode in a long while, so perhaps there's something else positive that I've forgotten.
Answer your question?
I guess I could have called my category 'might have worked with a better script editor'.
