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.

Adaptation Displacement: Few people who have seen the film , especially non-Francophones, will have read the novel it is based on, Un long dimanche de fiancailles by Sébastien Japrisot.
