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: Anyone with autism or a similar condition who can relate to this film a bit more will find Temple's panic attacks too close to home.
Even someone without autism or bipolar disorder or anything can find Temple's panic attacks scary as all hell, especially Temple screaming to her aunt to close the machine on her body while crying and screaming.
Nausea Fuel: The ranchers covering Temple's front window with bull testicles.
Made worse in that Temple just wipes it off with her hands and sleeves as if it were just mud. She even throws a little!
Values Dissonance: A major theme in the movie. The differences now and in the 1950's/1960's in our understanding of autism is the obvious example. However, another example occurs when she is living with her aunt at the cattle ranch, where the ranchers constantly mock her desire to work in cattle ranching, because she's a woman.
The Woobie: Beautifully averted by Temple, who's never portrayed in an overly sympathetic nor sentimental manner. We see her as a flawed but nonetheless remarkable woman, reacting naturally and realistically to difficult situations, while maintaining a clear sense of pride and a level-headed attitude throughout.
