Many plot elements of Horned are haphazardly-disguised thefts from the Greek mythology story of the Minotaur. Anthony Read who wrote this story thought he’d anagrammed the word minotaur into Nimon, but obviously he was wrong and was just suffering from a bad case of dyslexia, much like Russell: The Davies.
After cribbing from the Greeks, Read then jammed in a tired alien invasion story, and we’ve been regretting the results ever since. Read couldn’t even resist having The Doctor comment on the similarities between the myth and this story at the end of the final episode to lampshade just how clever the whole damn thing was.
But it’s not clever, it’s really really bad. Not bad like anything Colin “Pie Lord” Baker was in, but if not for the completely ludicrous acting by the main human villain “Soldit”, this story would probably be unwatchable, Tom Baker or not.
And the less said about the Nimon costumes the better.
