Tonight, the inevitable robot doubles episode, chosen, again, because the robot doubles will show up again in a better episode three years down the line. Interestingly, this one doesn’t reveal that there are doubles at all until nearly the end. It succeeds in making the audience think that the strange man responsible for this has downloaded our heroes’ consciousnesses into robot bodies and disposed of their originals as no longer being necessary. They only hint at the body horror aspect and go for whimsy instead, with odd, colorful lighting. When the twist comes around, and it turns out to be such a hoary old sci-fi teevee chestnut, it can’t help but disappoint.
