Espisode played purely for laughs as that zany green alien woman we met before in "Wild Adventure" comes down to the planet to amorously pursue "brave, handsome" Dr Smith.
Athena (as the alien woman is known here) has her previous suitor in tow and he's a bit of an uncivil barbarian type who likes to growl a lot, particularly in a menacing manner at Dr Smith. In fact you might say he's green with envy at Athena's attractiveness to Smith.
Will gets in a bit of a pickle too, but generally the Robinson family are relegated to incidental scenes. Although we do see quite a good scene where Don removes a broken down "Atomic cooker" from the Jupiter 2 using a nuclear glove box. Only two problems there are firstly that the camera zooms out to expose the supposedly hermetically-sealed nuclear compartment as really just a flimsy panel, with no side on it. Second problem is that if the stove is really that radioactive, then I'm surprised the family still have any hair left after eating meals cooked in that thing! But, I actually quite enjoyed this episode, and there's a good bit where Dr Smith sees into the future and observes what he thinks is his own catastrophic demise. This device has been used in quite a bit of sci-fi since. So despite the overall silliness of this episode, parts of it could be considered influential.
Certainly not one of the best instalments from season two, but it gives us yet more amusing adventures focusing on Smith, Will and the Robot.
