A lot of (Rod Serling's original) "Twilight Zone" fans like the CBS RMT, the TWZ's "Lil' sis" in many ways.  (Not the least of which, being in the CBS stable, they used much the same wonderful background music.)  Some TWZ episodes made it to the CBS RMT, like Ambrose Bierce's "Occurrence at Owl Creek Bridge" and "The self-improvement of Salvatore Ross" (renamed "A bargain in blood" for the RMT).

This particular episode is fascinating in that it was all but directly influenced by the memorable original-season Twilight Zone episode "The lonely"...yet it's told completely in REVERSE.  A different setting (modern America for "Life Blood" vs. a prison asteroid on "The Lonely"), different people (Apparent Nobel-level physicists and physicians vs. a convicted murderer), the "plot twist" Darryl B. speaks of (won't give it away, but there was no such problem in "The lonely", and in fact, a different ending ostensibly resulted because of it) and most importantly, the timing of the surprise (in "The lonely" the protagonist, played by the enjoyable, late Jack Warden, learns his "lady's" secret immediately...in "Life Blood", the secret is the story).

Troubling subplot: on first hearing the character of the wonderful John Beal, he sounds like a kind, loving uncle, but when you carefully listen to what he apparently has told his "niece", it seems all but evident that he's abusive.  Not sexually, but emotionally.  And as Gordon Gould's character in the play all but says: he created a lifelike, beautiful female android just for THIS?!?!
