I love Columbo, even though it’s formulaic; even though it breaks the rule of murder mysteries by revealing the killer at the start; whatever flaws it has, I can still enjoy watching it.
Except the episode named Mind Over Mayhem. It’s terrible.
The victim is killed because he knows the murderer’s son plagiarised a ‘theory of molecular structure’ (only a few centuries late)
A child genius enters three completely banal facts about the crime into a computer terminal and expects a solution (the response given by the computer is ‘does not compute’ Gah!)
Robby the Robot (or the top half of him, anyway) appears in earnest as a fully functional robot, capable of understanding complex natural language commands.
I know it was 1974, but wow, that’s the worst episode, for me.
