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: The Colour Out of Space

The moving trees at the climax were seriously disturbing. They're a prime example of Lovecraft's "just fundamentally wrong" sense of horror.
"And yet amid that tense, godless calm the high bare boughs of all the trees in the yard were moving. They were twitching morbidly and spasmodically, clawing in convulsive and epileptic madness."
Woobie: It's difficult not to feel terrible for the Gardner family - not just because of their horrible fate, but because of how helpless they are to stop it as it slowly approaches.
