    Aliens trap Dr. Smith and examine him. They need a new brain to power their ships computer. Dr. Smith convinces them that Wills' brain will be perfect for their needs. Once he delivers Will to the Aliens they discover he is a perfect match for their needs if it wasn't for his pesky feelings for his family.

    This is another serious episode that shows the path the show was going to take until the stuido wanted more camp to compete with Batman ratings.



    The Aliens in this episode always gave me the creeps as a kid as well as the weird organic look to their ship.moreless

    One of my favorites from the series, and one of the better "Sci-Fi" episodes. The aliens are very well done, much different from the "rubber suit" monsters which would dominate later in the show. The alien spacecraft is very well realized as well. Later on in the series alien ships were either not shown at all, or represented by stock footage from "Welcome Stranger". I don't think the episode is campy as some have stated. Sure, the science is dodgy, but I think the episode stands up pretty well. It's kind of reminiscent of 50's sci-fi. Yeah, if you really think about it's kind of goofy but it sure is fun!moreless
  • Another example of what Lost In Space could have been.

    A wonderful episode that centers on the greedy, conniving Dr. Smith. In this one, Smith the eaves-dropper is first seen watching the arrival of an alien ship. The ship detects his presence and "catches" him. A conversation ensues in which the aliens explain that they will use his brain to replace a computer on their ship. Smith tries to bargain his way out of it, but the aliens kidnap him and he's aboard their ship. Had Don West been there, he would no doubt have considered it fitting that Dr. Smith was kidnapped and therefore no longer with the Robinsons. Although Don West might have wondered why intelligent aliens would want anything that was in Dr. Smith's brain...



    If Dr. Smith is anything, he is amazingly good at his ability to wriggle out of a situation, wrangle someone else into it, and artfully lie about his involvement in the whole thing. Smith talks the aliens into letting him bring Will Robinson to them. They put a ring around his neck, and choke him with it, telling him that this will be a warning against betrayal.



    We get to watch Smith connive and wriggle his way around everyone, ultimately getting Will to go along with his deception. When the aliens trap Will aboard, John, Maureen, and Don, who had been looking for the missing Will, appear on the scene. When they confront Smith, we again watch him dodge blame by pretending that the whole thing was none of his doing at all. He exclaims that they got Will despite his best efforts. In the end, Will's tears foul their systems, and the more sympathetic of the two aliens orders the other to let Will go. The alien vessel explodes as Will appears in the nick of time. I always liked the scenes where John and Maureen are in the Chariot. Will, who is nearby, hears the echoing, booming, loudspeaker type voice of John repeating "Will...Will... Answer if you hear me". I think this is the only time that this feature of the Chariot was used. I don't know why that has always impressed me, but I like it for some reason.moreless
  • Dr. Smith takes over as the lead in the first of the camp episodes that would take over the series.

    5.6
    This episode demonstrates that Dr. Smith should have been on the receiving end of a laser pistol. Because of his own threatened mortality he has no problem exploiting the children of the ship to serve his own ends. I can almost understand Dr. Smith's turn to camp because a logical question of why don't we kill him will get overwhelming. Turning it into camp subdues that problem and makes the series more watchable (but less enjoyable in my opinion) This is apparent in this episode where Dr. Smith sells out young Will Robinson to preserve his own hide. The creatures from the 'fifth dimension' are swallowing a lot of bad dialog. There is a commentary about the human race but otherwise there is a lot of somewhat scientific silliness. I especially love it when John Robinson states that he understands the mechanics of the fifth dimension villains. I'm glad someone does! Note in this episode more stock footage from the unaired pilot for the chariot and jet pack sequences.moreless
