Will discovers an apparently inert 'robotoid' (played by Forbidden Planet's 'Robby the Robot') that, when reactivated, inveigles his way into the Robinson's trust (but not that of their trusty B9 unit) as part of a plot to kidnap the family. The two robots, both designed by Robert Kinoshita, are genre icons and it is fun to see them together even if the titular 'War' is more robo-psychological than robo-physical. The character of the Robinson's mechanical sidekick continues evolve, becoming more emotional and 'human' as he (along with buddy Will and 'frenemy' Dr. Smith) becomes more central to the show's plotlines (at the expense of the other characters). The limited resources available for new effects are evident in the laughable 'alien master' who is directing the treacherous tin-man from afar. The series opens with an odd scene of Will and Smith returning with some fishin' poles and a string of fish for Maureen to cook (her main space-activity when not tidying up, puttering in the garden or 'doing' Judy's hair), odd considering that only a few episodes back, the lack of local water put the entire family in danger. The episode would have been more memorable if the final robo-showdown had been a bit longer and more 'action-packed'.
