The term "taboo" refers to something that is widely considered to be unacceptable, forbidden, or prohibited by society. Pure taboo, in a sense, implies a complete and utter ban on a particular subject or activity. These subjects often carry a heavy stigma, and discussing them openly can make people uncomfortable.
Examine mainstream and indie films (non-adult) from 2021–2022 where protagonists cross moral or social lines because they believe they have “nothing to lose.” Examples might include The Novice (2021), The Worst Person in the World (2021), or Emily the Criminal (2022). Compare their emotional arcs to the “pure taboo” label in cult cinema.
