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.
YMMV: Rear Window
Hilarious in Hindsight: Stella questions how Thorwald, would've killed his wife. "Of course, the bathtub! It's the only place he could've washed the blood!" What other Hitchcock film was released six years after Rear Window? Psycho.
Nightmare Fuel: Thorwald's off-screen murdering of his wife and how he apparently chopped her body parts into individual pieces. There's a brief implication that the item he had stored in his hatbox was her head.
