This last episode of the series seems to bring together all the typical tips of the science fiction series of the 60s: aliens with the ability to convert their physiognomy into that of humans, protagonists moving in a world of immobile people, an android communications center , and a whirlwind that blows everything away. Everything that in Lost in Space looked childish and ridiculous was shown here as threatening and dangerous. An hour of pure entertainment without too many pretensions.
