These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Nightmare Fuel: The doctor being killed by being trapped in his car while the radio plays so loud it bursts his eardrums is genuinely disturbing.
Nightmare Retardant: Arguably, the doctor was killed because he was forced to listen to a song / genre of music he didn't care for.
One-Scene Wonder: Future big time director Barry Levinson is cast as a high-strung bellboy who gets progressively more irritated with Brooks' requests for a newspaper until he goes in Norman Bates-mode. It is considered among the most memorable scenes of the film.
