* Just the idea that men would kill their wives and replace them with lifelike robot replicas, and [[EvilIsPetty for no other reason]] than that they didn't like that their wives were autonomous human beings with their own personalities, thoughts, and feelings.
** During the climax, when Joanna despairingly asks ''why'' they'd do something like this, Coba, the BigBad just responds [[ForTheEvulz "Because we can!"]]
* [[https://www.youtube.com/watch?v=VG7JAM6DQnM When Joanna confronts Bobbie at her house,]] she becomes increasingly upset that she is refusing to communicate with her properly, and is acting way too differently than how she was before (for example, suddenly not knowing what "archaic" means). Eventually, Joanna grabs a knife and cuts her fingers, arguing that she can bleed... but then asks if ''Bobbie'' can. She then proceeds [[JumpingOffOfTheSlipperySlope to stab her]].[[note]]Katherine Ross couldn't bring herself to actually use the knife; the hand shown using it is director Bryan Forbes' shaved hand.[[/note]] [[WhamShot Bobbie doesn't.]]
-->'''"Bobbie"''': (annoyed) ''Joanna''... (removes knife)
** It gets worse: she proceeds to berate Joanna... except, as the scene goes on, she begins [[BrokenRecord repeating herself more and more]], dropping mugs and spilling coffee powder, and spinning around the room [[RoboticReveal like a broken robot]]... And all Joanna can do is leave the kitchen, horrified.
--->'''"Bobbie"''': (grabs mug) How could you do a thing like that? (drops mug; grabs new mug) How could you do a thing like that? (drops mug; grabs mug) How could you do a thing like that? (drops mug; grabs spoonful of coffee powder) When I was just going to give you coffee. (spills powder; grabs more powder) When I was just going to give you coffee. (spills powder; grabs more powder) When I was just going to give you coffee. (spills powder) I thought we were friends. I thought we were friends. I was just going to give you coffee. (opens and shuts refrigerator) I was just going to give you coffee. I thought we were friends. (opens and shuts refrigerator) I thought we were friends. I thought we were friends. (opens and shuts cabinet) How could you do a thing like that? [[JumpScare (turns and looks into camera) I thought we were friends.]]
** This is parodied in the remake, when Joanna is outright horrified to walk into Bobbie's now spotless kitchen, a complete 180° from the mess it's been before. Without even seeing Bobbie yet, Joanna realizes that she's fallen victim to the Stepford phenomenon too.
* While sneaking in to the Men's Association to find her children, Joanna follows the sound of her daughter calling for her, only to find it's just a recording of the girls voice playing in Coba's office. [[FridgeHorror When and where exactly did Coba record her calling for her mother?]]
* The [[BlackEyesofEvil eyes]] on Joanna's unfinished robot double, which you can see on this page.
** Even worse with the [[SlasherSmile smile]].
** There's something disturbing about the way the camera pans over the doubles larger breasts, like it emphasizes the monstrous, shallow pettiness behind it's creation even more. If you're already going to replace your intelligent, independent wife with a submissive robot, might as well spruce up other parts as well, right Walter?
** The last we see of Joanna is her staring in horror as her robot double approaches her with a serene, empty smile, while clutching a nylon stocking in her hands, preparing to pull a KillAndReplace on her. It then cuts to the Stepford grocery store where "Joanna" is shopping, dressed exactly like the other Stepford wives, vacantly greeting the other wives as they wander among the store shelves. [[TheBadGuyWins The credits show a smiling, unapologetic Walter picking her up in the family car.]]
