The best episode of the final season?
3 May 2007 | by (United Kingdom) – See all my reviews

Anti Matter Man is a wonderful, almost perfect episode. It stands out in an erratic season of episodes. Some of this season had good shows , but it also featured some truly low points ( A day at the zoo, Great vegetable rebellion, to name just 2!) But this episode is superior to any other 3rd season show, Sutton Roley directs assuredly and imaginatively from a script by K.C.Alison ( Robert Hamner and Barney Slater )It is a great pity Roley only did a handful of episodes- everyone he did was good if not great. The story may sound old hat- John Robinson is transported to the anti matter world inhabited by his evil alter-ego, leaving John there in the custody of Don West's alter-ego- the double takes John's place with his family.This episode really is tense, grim and features the comedy scenes in the right proportions and not too often. Several scenes stand out- the evil John virtually clubbing The Robot to pieces, again the evil John stalking Will Robinson through space on an eerie stairway of mist and light, the 2 John's fighting in space amongst a myriad of lights.Dr. Smith, Will and The Robot travel to the anti matter world to find the real John Robinson, their adventures along the way are fascinating.A prime example of the perfect Lost In Space. Check it out.
