  • Attack of the carpet barf!

  • Is the Horta costume better than the original Godzilla's? Maybe.

    Always considered this one of the worse episodes in the series, surprised how many high ratings it has been given. Granted, the story is ok; humans intruding in some creature's habitat and reaping the consequences, then finally learning to co-exist after smothing out some bumps.

    What bothered me is when the miners come across these dense spheres (Horta's eggs) and don't bother studying them, they simply move them, which causes the "mom" to come looking for its eggs and in the process kill a few humans. You would think people capable of interstellar travel would be a little more curious and (at least) study the spheres.

    The part that's really laughable is the Horta costume; simply a rug thrown over some stunt person. I realize this episode was filmed over 40 years ago, but come on! They could have done a little better...

    Oh yeah, I almost forgot; the part where Spoke mind melds with the creature and finally learns that it's distraught about its missing brood. The way Spok screams PAIN!!! PAIN!! over and over is just plain bad acting on the part of Leonard Nimoy. The director dropped the ball on this one, should have done more takes...moreless
  • Kirk and Spock attempt to reason with a creature that has been killing people.

    This is one of the episodes of Star Trek that made me a fan of the Original Series. It was written by Gene Coon, perhaps the best writer on the show; certainly second only to Gene Roddenberry when it came to developing Star Trek's stories the first two seasons. The episode begins as a horror episode, with a monster attacking people. But instead of leaving it at that, Star Trek takes the next step and asks, "Why is it attacking people?" In doing so, it throws it throws out some interesting science fiction ideas. The episode mostly centers around Kirk, Spock, Bones, engineer Vandenberg (played by guest star Ken Lynch) and, of course, the monster. Leonard Nimoy deserves special mention; as Spock (and the monster) he knocks it out of the park, giving another outstanding performance. All in all, a great episode.moreless
  • Miners on Janus VI get scared by some guy crawling under a poorly constructed turtle costume

    What a beautiful message, really. I love the occasional theme in Star Trek that peace and beauty among other things are not always easy to see by mere appearance. I read it was one of Shatner's favorites with the additional side item that he lost his father during the shooting of this episode and the crew was quite supportive to him. I have used the "Horta lesson" many times in my life on misjudgment of character and behavior of people and situations. The creepiness and terror of this episode is overcome by warmth. What a nice idea.moreless
  • Kirk, Spock and McCoy investigate a series of incidents on a mining in which workers have been killed by a seemingly hostile subterranean creature. Although it looks somewhat cheap and dated in places, mostly a good episode...moreless

    (Note that, as with all of my 'Star Trek' reviews, I am reviewing the original versions; I have not yet seen the remastered versions).

    I have been watching 'Star Trek' since I was very young, thanks to my father who was a casual viewer. When I started to really get into it during my teens, this episode stuck in my mind as being one of my favourites for whatever reasons.

    Something that works against this episode somewhat is its cheap and dated look. In most cases, I will defend original 'Trek' episodes, as I believe they mostly worked wonders considering the technical limitations of the time, not to mention the usually tight budget. But I have to admit, this one looks a bit ropey in places.

    A key example of this is the backdrop to the mining colony; while elsewhere in the series we are treated to some stunning matte backdrops, this one sadly just looks like a cheap painting, and looks very unconvincing.

    The caves too aren't the best (looking distinctly like paper mache in places), and the creature itself looks like something from a weaker moment of vintage-era 'Doctor Who'. Some episodes have dated better than others, and I have to say, time hasn't been very kind to this one.

    But for all that, the episode is redeemed by being a really good story. Look past the dodgy effects and sets, and this is a great piece of 'Trek' writing and direction.

    Unusual with this episode, is that it features extremely little of the Starship Enterprise. The entire teaser does not feature any crew members – a rarity in itself – and we only get a brief Enterprise scene at the start of the second act, and in the final, obligatory "all laugh at Spock" scene.

    William Shatner has commented that this is his favourite 'Trek' episode, and in many respects I can see why. It is an interesting story, with an interesting twist in the tale, which makes you question just who the real villain of the piece is. Where other shows would dish up standard 'monster of the week' stories, 'Star Trek' would offer up more thoughtful – yet none the less entertaining – tales such as this.

    Talking of Shatner, I did notice in a number of shots from behind that it was a double in his place. This would be explained by the fact that his father passed away during filming of this episode, so a double was used in rear shots to allow him some time away.

    As I say, as a teen I really liked this story, and I still enjoy it. There are a couple of moments where things slow up a little (heck, that's the case in many episodes), but if you're prepared to forgive the dodgy effects and sets, this is a really good episode.moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (11)

    • Lt. Commander Giotto wears full commander stripes.

    • Several times in this episode, Kirk uses his communicator and it doesn't "chirp" when he opens it.

    • Vandenberg opens the door to his office with a button on the underside of his desk - at different times he presses different spots on the desk.

    • Why did the Horta steal the reactor pump rather then destroy it? It's trying to kill the miners or get them off the planet - what advantage is there for the Horta to save it?

    • How did the Horta know exactly what part to steal? It's smart, but it doesn't seem to be familiar with human technology.

    • During the confrontation with the Horta with Spock and Kirk, in one shot, Kirk's phaser is up, and the next shot, the phaser is down to his side.

    • While Kirk is waiting for Spock to arrive, after his meeting the Horta and sitting down, we see him holding his phaser pointed at the ground, near his waist. We then cut to a wide shot when Spock comes in and we see Kirk holding his arm stretched out, only this time he is holding his communicator. Then we cut back to a close-up of Kirk and his arm's holding the phaser again, pointing down.

    • When Spock and Kirk pursue the Horta, they come to a fork in the tunnel. Kirk points right and tells Spock to go left. Then he points left and says he'll go right.

    • Spock informs Kirk that the Horta excretes a highly corrosive substance that lingers on the tunnel walls, yet in later scenes a portion of the creature and eventually the creature itself is touched with no ill effects.

    • The Horta's tunnels don't match the shape of its body - watch the one scene where we actually see it going down one of its tunnel. The Horta is kind of oval/elliptical, but the tunnel is perfectly round and several feet higher than the top of the Horta.

    • For all their high-tech advances, McCoy uses a plastic yellow bucket to hold the thermo-concrete he uses on the Horta.

  • QUOTES (7)

    • Vanderberg: Look, we didn't call you here so you could collect rocks!

    • McCoy: He's dead, Jim.

    • Spock: If it is the only survivor of a dead race, to kill it would be a crime against science.

    • McCoy: [after being asked to treat the Horta] I'm a doctor, not a bricklayer!

    • Spock: The odds against both of us being killed are 2,228.7 to 1.
      Kirk: 2,228.7 to 1? Those are pretty good odds, Mr. Spock.
      Spock: And they are of course accurate.
      Kirk: Of course. Well, I hate to use the word, but, logically with those kinds of odds you might as well stay. But please stay out of trouble, Mr. Spock.
      Spock: That is always my intention, Captain.

    • Kirk: Think she'll go for it?
      Spock: It seems logical, Captain. The Horta has a very logical mind. And after close association with humans, I find that curiously refreshing.

    • Spock: Curious. What Chief Vanderberg said about the Horta is exactly what the Mother Horta said to me. She found humanoid appearance revolting, but she thought she could get used to it.
      McCoy: Oh, she did, did she? Now tell me--did she happen to make any comment about those ears?
      Spock: Not specifically. But I did get the distinct impression she found them the most attractive human characteristic of all. I didn't have the heart to tell her that only I have...
      Kirk: She really liked those ears?
      Spock: Captain, the Horta is a remarkably intelligent and sensitive creature with impeccable taste.
      Kirk: Because she approved of you.
      Spock: Really, Captain, my modesty...
      Kirk: Does not bear close examination, Mr. Spock. I suspect you're becoming more and more human all the time.
      Spock: Captain, I see no reason to stand here and be insulted.
