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: What A Nightmare Charlie Brown
Nightmare Fuel: Snoopy is abused and starved, becomes evil, and then dies getting pulled into a frozen lake (alongside the other sled dogs and the cruel master), screaming and clawing for his life. Granted, the special establishes from the start that it's All Just a Dream and none of it is really happening, and there is some comfort in the happy ending with Snoopy eating ice cream and being allowed to sleep in Charlie Brown's bed for the night, but still... one could argue that this was inappropriate for the Peanuts specials' target audience.
