YMMV / The Quiet Ones

• Moral Event Horizon: Professor Coupland firmly crosses it when he loses his temper and physically assaults Jane although (in an in-universe sense), he already crossed it with Brian when he tried to burn her arm during a session.
• Narm: Thanks to the rampant fakeouts with the jump scares, moments that were supposed to be played off as suspenseful and frightening later on in the film will only meet with an already jaded audience.
• They Wasted a Perfectly Good Character: The student who gets downright antagonistic with Professor Coupland at the very start of the movie (and much later on with Brian at the library) could have been a potentially poignant moral foil to the experiment, especially when the latter begins to cross the Moral Event Horizon by harming Jane to get results. He doesn't appear for a minute in either of his scenes.
• Too Dumb to Live: Krissi. Evey tries to kill her twice, and she even acknowledges it. Despite that, instead of going into hiding as far away from Evey as possible, she goes back into the household, which gets her brutally killed.
• Took the Bad Film Seriously: The film itself is pretty forgettable, but Sam Claflin and Olivia Cooke give it their all anyway, turning in legitimately great performances.
