Warning: Spoilers for "Promising Young Woman" incoming.
Revenge stories are a classic in movies. Usually they involve some wronged manly man who then goes on a rampage to rectify things, usually by killing everyone, which somehow makes it okay. Look no further than half the filmography of Gerard Butler (especially the atrocious "Law Abiding Citizen"). Tarantino mixed the genre up by switching the manly man into a female woman, but that has gone stale since then, too.
