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.
Award Snub: The movie was not submitted by Switzerland for this category, more or less due to its being a Swiss-French-Pole co-production. It was nominated for Director, Original Screenplay, and Cinematography, but lost all three (to Forrest Gump, Pulp Fiction, and Legends of the Fall respectively).
The trilogy as a whole provides examples of:
The Woobie: Julie in Blue, Karol in White, and Kern in Red. They each end up more-or-less happy (well, sort of) in the end.
