The Enterprise explores a planet where only children have survived a horrific plague that wiped out the adult population. With the landing party themselves now infected, and no access to the Enterprise after the game-playing children stole their communicators, only a few days remain to discover a cure.
I left out of my little recap any mention of how this episode opens: when the Enterprise finds this alien world, they discover it to be an exact copy of Earth, right down to the continental formations. I omitted this because it ends up having absolutely no bearing on the plot. Nor is any attempt at an explanation ever offered. That's because surely such a provocative story element wasn't actually part of the original idea; instead, it was wedged in at the end to justify how the entire episode could be shot on the standing city sets of the studio lot -- without altering the building appearances, scattered props, or English writing.
It's nearly impossible to ignore the fact that this episode casually discards the most interesting aspect of the story. Yet ignore it I must to get on with the rest of the review. But before that, I will at least acknowledge that, having stuck this "devil's bargain" to be able to film on existing sets, "Miri" absolutely makes the most of those sets. We get sweeping overhead shots of the outdoors, the interiors of multiple buildings... generally, a massive scope to this mission that very few Star Trek episodes could really touch until the "volume" technology of modern day allowed sets to incorporate CG directly on the filming stage.
What we get is the first genuinely strong showing for the character of Dr. McCoy. Not only is he able to cure this alien plague and save the day, he tosses off the sort of trademark quips along the way that we'd come to know him for. (When tasked with making a vaccine, he tells Kirk: "Is that all captain? We have five days you know.") McCoy is also ultimately willing to test that vaccine on himself when it appears someone will have to be the guinea pig. Plus, his verbal jousting with Spock feels genuinely playful in this episode -- not as harsh as the "this is actually racist, right?" tone that sneaks into some other episodes.
Unfortunately, the rest of the episode now stands as a rather uncomfortable artifact of its time. If this episode were made today, you'd hope that Kirk would attempt to gently-but-firmly shut down Miri's adolescent crush on him, rather than smile creepily at her and call her pretty. (Her reaction to being "spurned" could still lead to Miri's double-cross, as the story demands.) If made today, you certainly wouldn't see Yeoman Rand breaking down about how the legs she's desperately been trying to get Kirk to notice are now marred with plague marks.
Maybe the modern version would take a little more time to explore the question of how the "Onlies" of this planet could live 300 years and still behave as they do -- is the child brain truly incapable of any "grown-up" thinking? (On this planet, at least?) And maybe we could button up some of the plot holes. Why does Yeoman Rand go on this mission? (It's not like she goes whenever the captain does.) Why does her abduction by the Onlies take place off-screen? Why does the Enterprise not try to do anything after not hearing from their landing party for days?
Other observations:
- Today, we take for granted that the core original crew was Kirk, Spock, McCoy, Scotty, Sulu, Uhura, and Chekov. But there are other minor characters repeating too -- like Farrell, who has inexplicably moved from the helm in a previous episode to the communications station in this one. If that guy had popped, maybe today we'd know "Jim Goodwin" as well as we know "George Takei."
- This is a major episode for musical score. Several themes make a first appearance that would get tracked in for all sorts of later episodes and situations.
- Michael J. Pollard, who plays Jahn, is one of the most familiar-looking "that guy"s you'll find in Star Trek. His list of credits is a mile long, but I know him best from his appearance in Bill Murray's Scrooged.
- Classic Star Trek has a tendency to ratchet up the jeopardy with a bit too much hyperbole. Here, it's mentioned that the children on the planet -- who have lived for centuries -- are going to run out of food in a few months. As if the plague that will eventually kill them all isn't enough.
- Spock's musing that McCoy may have created a "beaker full of death" gives us a great band name.
- In a reminder of just how many details about Star Trek weren't set in place from the beginning, Kirk says at the end of the episode that he has contacted "Space Central" -- what presumably became "Starfleet Command," once all the trappings of the universe were locked in place.
Because this is an early milestone episode for McCoy, there are elements of this episode I truly like. But with so much of the rest of it evoking an eye roll or a cringe, I think "Miri" caps out at a C+.
