When the Enterprise answers a distress signal from a mining colony that is being terrorised by an unknown monster that has so far killed over 50 people, it at first appears that we are in for a re-run of “The Man Trap”. At first, Kirk is again pretty gung-ho in wishing to hunt down and kill the creature, despite Spock’s concerns when he theorises that this could be the last of its kind. But, fortunately, we do see that Kirk isn’t quite so simplistic despite his “shoot to kill” reputation, and the script cleverly undermines out expectations as Kirk attempts to understand the creature and it turns out that it was only killing the humans since the colony was threatening its eggs. As such, this is probably the most archetypal Star Trek story so far, using the an analogy involving a blobby monster to show the penalties of fear and the benefits of empathy and trying to understand your enemy as we get a happy ending as both human and creature attempt to understand each other and compromise in order to get a happy ending that benefits everybody. The concept is not dissimilar from “Arena”, but it is handled more successfully here in the context of the tropes of a conventional monster movie.
The episode takes place almost entirely upon the mining planet of Janus V. The tunnel sets are surprisingly impressive, although this is undermined somewhat by the floor being unnaturally flat. They are also very brightly lit, so there isn’t a lot of menace in the sequences where various people are in danger of attack. The design of the creature, named as a Horta, is also surprisingly effective – it is clearly a man crawling on the floor whilst covered by some blobby plastic, but it isn’t completely comical and I actually found the scene where it cowers from Kirk’s phaser quite affecting.
Even though this is very clearly an episode with a message, it still manages to very entertaining, despite the fact that not a lot actually happens and there are an awful lot of scenes of people wandering around cave tunnels. It is also not an episode that should be thought about too closely. The tactics of the colonists are somewhat reckless – continuing to post lone sentries in areas of danger despite the fact that 50 people have already been killed (although Kirk essentially does the same with his security officers). There is also yet another countdown to danger when the Horta steals the main circulating pump from the colony’s nuclear reactor with the effect that it will soon go critical. This artificial time limit isn’t really successful in introducing any additional tension and it does raise all sorts of questions, such as why the colony doesn’t have a spare of such a critical component and quite how the Horta was able to delicately remove and transport it, despite being just a blob of rock.
In terms of the regular cast, the focus here is very much on Kirk and Spock. At one stage, it looks like there is going to be conflict between them over whether or not the Horta should be killed, leading to an odd moment when it appears that Kirk is attempting to marginalise Spock’s involvement in the hunt for the creature in order to stop him from interfering. But this doesn’t really come to anything, with Spock actually agreeing that it is necessary to kill the creature in order to protect the colony. Ultimately, it is very convenient that Spock is present since it the use of a Vulcan mind meld (although not yet named as such) which allows Kirk to understand the Horta’s motivations. The mind-meld gives Leonard Nimoy another reason to do some un-Spock-like emoting as her feels the pain of the Horta, although this doesn’t seem that unusual coming so soon after “The Other Side Of Paradise”. DeForest Kelley doesn’t have much to do in this episode, but he certainly has an impact. His reaction is priceless when Kirk asks him to treat the injured Horta, and his line “I’m a doctor not a bricklayer” will of course go on to spawn a number of variants in later episodes. But his joy when succeeding is infectious and he is given another line which was already familiar to me despite this being my first viewing of the episode (“By golly Jim, I’m beginning to think I can cure a rainy day!”).

Planetary Gazetteer
Janus VI: A mineral rich planet on which the Federation has established a colony and a production facility for the mining of pergium, an element that is used as fuel for nuclear reactors. The planet is home to the Horta, an intelligent silicon-based lifeform that emits a corrosive acid to allow it to move through rock. Every 50,000 years, all of the Horta die apart from one individual which is responsible for caring for thousands of eggs that will repopulate the species.General Observations
- A single Stardate is given in the episode – 3196.1.
- Neither Sulu not Uhura appear in the episode. The absence of Nichelle Nichols means that there are no female speaking parts in the episode and the only time that we see any women on screen is in the background of the brief closing scene on the bridge.
- We see the largest number of Enterprise security officers yet – initially a team of six (one of whom is killed by the Horta) and then eight, all led by Lt Cdr Giotti (who appears to the Enterprise’s chief of security). The security officers aren’t that effective since they are somewhat easily overwhelmed by a few colonists wielding sticks.
- This episode introduces some terminology for the two type of hand-held phaser that we see being used during the series – the small devices are called “Phaser 1” and the pistols are “Phaser 2” and are more powerful.
- The scene where Kirk is confronting the Horta includes a number of shots for Kirk from behind when this is clearly not William Shatner. This was to cover for Shatner’s absence during part of the shoot due to the sudden death of his father.
