    "The devil in the dark" is still my favourite episode!

    This may not be the most exiting or incredible episode they've made, but in my opinion it remains as one of Star Trek and the Sci-Fi genre's most original episodes. Most ideas from retro Sci-Fi series especially including Star Trek has been reused several times, this one the other hand remains mostly as a one time triumph. This among the episodes that impressed me the most towards the end.

    Another thing I like with this episode is how it has accomplished to create such and exiting and captivating story with such few special affects. Now without criticizing the episode I must admit the effects are very dated, but then again what can you expect from a TV show from 1967? But still the creature ("Horta") in this episode is basically just a carpet with some coloured rubber on it. Yet you forget this after about 1 minute and you only start thinking about it as what it's supposed to be. Also the caves don't exactly look like rock, but again you forget it after a few minutes. This episode is a living proof on how good acting and a good story, can make you ignore the visual effects.

    The acting from the main cast is as usual great. This episode features the series second mind meld by Spock and is one of my favourites. So to say it simple Leonard Nimoy is definitely a scene stealer here, and his acting is excellent. Not that Kirk or Bones don't get their share of the episode but Spock is the most intriguing in this one. i like the fact that the episode is not about one specific character but evolves around the trio handling an alien problem. Also it's nice to see an episode who doesn't only happen on the Enterprise.

    Like most Star Trek episodes this episode tells us to have an open mind. I won't spoil the story, but evolves around what in the start seems like a typical monster story. It has killed several humans and therefore must be killed. But is that really all there is to it? I can assure you that the explanation in the end, will not disappoint you. This is still my favourite Star Trek TOS episode and i give it a 10/10.

    The Horta, not life as we know it

    Leonard Nimoy's Vulcan mind meld proves of invaluable assistance in this Star Trek episode. Life may not look anything like it does on earth and it may not even function bodily as we do on earth. But life can be found in the strangest of places.

    Consider this planet which looks to be made of solid rock, yet something is killing off the miners in Ken Lynch's crew. Which is why he sent a distress call and the Enterprise responds.

    Lynch's men are not being killed, in fact they're being burned to a crisp. It's being done by a creature we learn calls itself a Horta and to our eyes it's not aesthetically pleasing.

    This Star Trek story reduces life to a problem of communication. The Horta has a very good reason for doing what it does.

    It's a good moral this story has, all we need in the Universe is better communication.

    That's No Devil - That's a Horta!

    I sympathized with the plight of the first man, Schmitter, we see killed in this episode. He reminded me of the trepidation associated with being a lone security guard at night somewhere - the type of work I did briefly about 20 years ago. Of course, I was never in danger of being burned to a crisp, as the colony chief (Lynch) is fond of describing. The monster in the dark here, murdering members of a deep mining colony, creates a scary impression in the first act. We don't really see it in the early scenes and, as many of us realize, the best monsters are sometimes left to the imagination. 'Big and shaggy' is one voiced description, but it actually turns out to resemble a big, lumpy pepperoni pizza, skittering along the ground like a silicon centipede - a limitation of the show's budget, unfortunately. This also shows in the latest matte painting, famous to Trek fans, the only way to convey a long shot of the mining operations.

    But, the whole theme of this episode is about what's on the inside, rather than outward appearances, anyway. Sure, this Horta, a newly-discovered silicon-based life-form, looks like a mindless monster at first glance. Thanks to Spock's telepathic ability (probably the best use of a Vulcan mind meld for plot purposes), we learn it's a highly intelligent, even sophisticated creature. Besides Spock's instrumental use of his talent, McCoy gets to supersede his usual medical routine - healing a creature resembling rocks or asbestos. He also gets to utter one of his most famous lines, "I'm a doctor, not a bricklayer!" I found it very true-to-life in his scene where he exults in his success, though he's unable to get Kirk to share in his enthusiasm - Kirk's too busy organizing results. The episode throws unexpected turns in character & motivation at the audience as the story progresses; Spock champions the need to possibly preserve this discovered life as Kirk takes his usual stand on preventing the deaths of any red-shirts (no half measures, as in "The Man Trap"). But later, it's Kirk who, for some reason, holds back on firing a killing blast, as if the heat of the hunt had worn off and he'd had time to reflect on Spock's point (I believe it was during this episode's filming that Shatner learned his father had died). Uncharacteristic for most of the first season, this has a happy ending. The conflict stems from the needs of basic capitalism, such as meeting standard quotas, versus protecting the natural environment and its inhabitants - a space age version of protecting owls from the tractors of modern advancement. Somehow, despite many killings and a sense that everything could go to hell at any moment with one raised phaser, Kirk and Spock manage to broker an agreement which satisfies everyone. I guess people and silicates are more reasonable in the 23rd century.

    "Just as any mother would fight to save her children..."

    In 1975 a friend of the family took me to a local JC in Sacramento for one of the first "Star Trek" conventions. I remember someone had taken some electrical tape and spelled out on the floor in the foyer at the convention entrance "NO KILL I".

    The homage paid by this act reflects the importance of the social trend and awareness happening at the time. The country (the western world in fact) had just come off of one social upheaval in the midst of the Cold War, and was entering another. Trek was ahead of the curve by telling another great parable regarding not just a conservationist message, not just an environmental message, but one that levels a finger at mankind in his treatment of other living creatures.

    This episode hits empathetic folks on a gut level. My mother included (or especially I should say), for while watching this episode with me (one of the few times she and I watched Trek together) she sternly agreed with Captain Kirk when Shatner's character berates Jarvis for the wanton and irresponsible acts of destruction.

    It's not just a warning for today's companies and their forefathers, however still relevant and timely. It's more than that. It's a future warning to mankind, and any sentient who would mindlessly exploit that of which they knew nothing.

    Another review comments on the thesping by Shatner and Nimoy. I agree that it's high caliber. The matte painting of the mining facility is what it is, as is the Horta itself. It is, after all, 1960's sci-fi TV. Even so, I'm hard pressed to find better props used in today's TV offerings (part of the reason I don't watch too much contemporary television anymore). Good shots, good dialog, good story, and a profound theme.

    Enjoy.

    Excellent Star Trek; one of my favorites

    Everybody likes to say how cheesy the monster looks. But I'll be honest. It still gave me nightmares at age 10.

    I also didn't like this episode much as a kid because we hardly see the Enterprise, and how can that be Star Trek? Eventually I learned that good science fiction, like all drama, is about characters and ideas, not sets and costumes and special effects. And so "Devil in the Dark" is now one of my favorite Star Trek episodes.

    I sometimes wonder if it was done as penance for "The Man Trap". That episode also featured an intelligent creature, native to the planet and the last of its species, who began murdering humans for no apparent reason. But that episode doesn't fit the Star Trek philosophy at all, while this one is among the very best examples of that philosophy in action.

    • Trivia
      In his book "Star Trek Memories", William Shatner identified this as his favourite episode, because his father died during filming and Leonard Nimoy's delivery of the mind meld lines made him laugh. He thought it was "exciting, thought-provoking and intelligent, it contained all of the ingredients that made up our very best Star Treks."
    • Goofs
      Using clubs to attack the Horta would make no sense. Since the Horta exudes an extremely corrosive fluid to create its tunnels, capable of dissolving large quantities of solid rock in seconds, all it would need to do to protect against the clubs is release a large quantity of the corrosive. Any kind of club used to attack the Horta at that point would simply disintegrate when it touched the corrosive on the Horta's exterior.

      [McCoy has been ordered to help a silicon-based life form]

      McCoy: You can't be serious. That thing is virtually made out of stone!

      Captain James T. Kirk: Help it. Treat it.

      McCoy: I'm a doctor, not a bricklayer.

      Captain James T. Kirk: You're a healer. There's a patient. That's an order.
