    Curing a rainy day

    Enterprise visits mining colony Janus VI.

    This is a classic episode with a brilliant message and a number of strong character moments.

    The plot is simple and highly effective with a powerful statement on humanity that embodies the best themes of Star Trek. It unfolds in a compelling way with Kirk and Spock at the heart of it, well supported by Bones and Scotty.

    Kirk is fantastically written, behaving in a way you would want someone of senior authority to act. There are no rash decisions. He is the ultimate cool head in a difficult and pressured situation.

    Spock is the catalyst for everything positive that happens. These are great moments that define his character. His level of humanity is laid bare in his compassion for life and his protective instincts towards his Captain. I love how he spins his obvious emotional response as defending science.

    Bones has rarely been cooler, particularly in his transition from seemingly lacking the confidence to do something to an almost god-like belief in his own abilities.

    I think what makes it great is that it is so different from most other creature-based sci-fi and adventure stories. It would be so easy to give in to the blood-lust of most film and television consumers and make it a 'fight the monster' story, but this one could not be more opposite.

    The visuals are mostly great. I love the set design, props and cinematography. The creature effects are very Star Trek. There's not much to say other than it is a stuntman underneath a what looks like a Persian rug decorated with foam pizza toppings. All part of the sixties charm.

    William Shatner and Leonard Nimoy both give strong performances, particularly Shatner under the circumstances of his personal life at the time. DeForest Kelley has a smaller role, but he has some classic lines. James Doohan is entertaining as ever and the guest performers are solid.

    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.

    Still a favorite after all these years

    Kirk and the crew are visiting a federation mining colony on a remote planet rich in mineral resources. The Devil in the Dark is the Horta, a very unusual silicon based life-form which tunnels through solid rock. The Horta has been killing miners and, it is decided, must be destroyed. But how?

    It is hard to continue this review without writing a spoiler, so instead I simply concentrate on the technical aspects of the episode and touch on its themes. The special effects are OK, but many of the scenes with the Horta look a little absurd. The acting is fairly average for TOS. Some of the miners are a little awkward. Nimoy has the most difficult role of all in Devil in the Dark, and he pulls it off well.

    Why is this still a favorite of mine?

    Devil in the Dark is really an anthropological and ecological morality play disguised as an adventure. More than many episodes of this great TV series, it brings home the importance of maintaining an open mind and at least some degree of empathy toward others. Plus, it involves one of the most interesting, if not probable, plot twists in the original series.

    Enjoy!

    "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.

    • 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: 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.
