Uncanny Village

A beautiful, seemingly utopian community which is not what it seems. Often either under control of a morally questionable conspiracy or demented super computer, or protected by a Deal with the Devil. May even be an entire town of Well Intentioned Extremists.

Not quite the same as Town with a Dark Secret as these are usually not particularly idyllic nor do they have The Village's uncanny quality. May overlap with Stepford Suburbia. Contrast Quirky Town. A Wrong Genre Savvy character may take it for a Close-Knit Community—or vice versa.

 * The quaint little town of Wychford in the Real Adventures of Jonny Quest episode "Village of the Doomed" turns out to be this (as if the title wasn't ominous enough). When Jonny and his father Benton Quest arrive at the town for a bonding fishing trip, the townsfolk all seem very nice and polite. Then the Quests get attacked by a rabid man and they find out he has a microchip implanted in the back of his neck, which can be activated to control his emotions and has malfunctioned, setting the man on a permanent Unstoppable Rage. They start to investigate the case. Turns out, Dr. Smallwood, the Mad Scientist who created the controlling microchip had been experimenting with all of the town's inhabitants, only everybody else's chips are set to "permanently nice" mode. Once Smallwood figures out that the Quests are sticking their nose in his business, he flips the switch on the chips, transforming the whole town into a horde of zombie-like, mindless, aggressive, drooling Mooks. Not quite the quiet vacation Jonny and Benton were hoping for.
