Good sci-fi plot
22 September 2010 | by benkidlingtonSee all my reviews

The opening sequence may seem like something out of Batman, but I enjoyed this one, because I like the story of the intelligent aliens intending to conquer the entire Earth. There's a lot more at stake here than just the safety of the Robinson family.

The bond between the family and the Robot is shown to be very great as they completely resist parting with him, regardless of the consequences and likewise the Robot chooses to sacrifice himself when the family are threatened. It's made pretty clear that the Robot has become as important as any of the other characters - a far cry from his simplistic interactions at the beginning of the first series.

But more than anything, this episode was way ahead of its time. The idea that technology of the human race is really a weakness as well as a strength, that this weakness could be exploited for malevolent purposes is even more relevant now than it was back in the '60s. Although, it's all done in a fun way here, as we can laugh as technology gone wrong puts various members of the Robinson family in serious peril.

The style of the aliens is also very creepy, the way they hang around in the shadows and sneak up behind people, and the way they sway sideways as they walk, it's all very atmospheric.

Without giving anything away, the ending teaches us that the robot has become more than the sum of his parts - he has developed emergent behaviour and effectively outgrown his original specification.

Perhaps the denouement is brought about a little too swiftly and cleanly though, but overall a good episode for season two.
