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.
Magnum Opus: Jimmy Stewart called this his favorite of the four movies he did under Alfred Hitchcock, and it also seems rather popular among Hitch's fans-Rotten Tomatoes gives it a 100% Certified Fresh rating.
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.
Special Effect Failure: Jeff falling out of the window looks unmistakably like a chroma key effect. Plus, when everyone runs out into the courtyard to see this, it seems pretty obvious that they filmed the scene at normal speed and sped it up in post.
