One of the rare times when Guy Williams got to be the "star"
27 September 2009 | by (Camilla, GA) – See all my reviews

Receiving top billing for all three years of the show's run didn't quite bode well for Guy Williams. Most of the episodes, from season two through three, focused on the Dr.Smith/Will/Robot trio, leaving the rest of the cast to have glorified "cameos". However, "The Anti-Matter Man" allowed both Williams and Mark Goddard (Don West) some choice scenes, playing their regular characters and the anti-matter world "opposites".

The episode also allowed for some intriguing set design, especially in the Dali-esquire-looking alternate universe. The installment made effective use of stock music from John Williams, much appropriate for several of the tense scenes.

Jonathan Harris's scene-stealing was kept at a minimum in the installment and that, by itself, makes this one a cut above others in the last year of Irwin Allen's classic.
