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: Waltz with Bashir
Animation Age Ghetto: The director had a great deal of difficulty getting funding for a serious documentary about a massacre that is also animated.
Nightmare Fuel: Most of the movie. The first scene with the monstrous dogs is an example, but by far the most disturbing instance is the "slaughterhouse", a place where the Phalangists interrogated Palestinian suspects, executed them and collected body parts as trophies. The whole scene looks like a terrifying bad acid trip.
