Does he use the N-word in every movie?
Is his usage of the N-word often completely unnecessary? I think so.
Reservoir Dogs - check. Completely unnecessary scene where Steve Buscemi's character talks about how niggers are unprofessional and always fighting.
True Romance - check. Now he didn't direct this but he wrote it. There's a whole speech about how 'niggers' polluted Sicilian blood.
Pulp Fiction - check. Tarantino himself shouting at Sam Jackson about niggers.
Jackie Brown - check. General usage by Chris Tucker and Sam Jackson.
Kill Bill 1 and 2 - one of the few movies I can't remember it being used at all but I may be wrong.
Inglourious Basterds - check. Only black character in the movie referred to as a nigger on several occasions.
Django Unchained - check. 'Nuff said.
The Hateful Eight - check. Right from the opening scene.
Once Upon a Time in Hollywood - can't remember. Only movie of his i've only watched once.
At best I think it's a minority of his movies where the word is required to tell the story. At worst it's completely unnecessary and I see why people get offended by it.
