The example that comes to mind for me right away of a movie that breaks form and genre is the movie Me Before You. I built up my expectations very high for such a romantic, sweet, and heart warming movie. However, my expectations were not met in the least. They were destroyed and left me quite confused and somewhat angry.
I would credit the producer and writer to really portray such a realistic ending, however, it did not fit the mood that I wanted to experience when I chose the movie, and I had to pay three dollars to be disappointed and sad.
The movie is set up for a classic enemies to lovers romance. The hopeless male who became paralyzed is helped by the optimistic, bubbly female who was hired to essentially be his friend and to help with caring for him. The plot reveals that her real job is to restore the male's happiness so that he does not choose to go on with planned euthanasia (as determined that he would choose in a certain time). One might expect, as the two become close and develop romantic feelings, that he would not go forward with the procedure. However, this is not the case. A movie that left me extremely confused and questioning the sanity of the writers and producers, Me Before You destroyed the expectations that I had, and did so in a way that I did not fully appreciate.
The movie was very good. However, I was taken aback, and would have chosen to watch something else with my mom so that we were not both crying on our mother-daughter romantic movie night.
