A Tale of Bloody Revenge
You could argue that vengeance was always present in Tarantino's work. Recall the criminals trying to find the rat in Reservoir Dogs or Marsellus Wallace's Pulp Fiction promise to ''get medieval'' on Zed's ass. But ever since Kill Bill, revenge has been Tarantino's essential cinematic plot point. Inglourious Basterds is centrally the tale of Jewish soldiers performing unspeakable acts on Nazis as a kind of wartime reparation; Django Unchained sets its hero on a mission to punish the men who took away his wife. Even Death Proof follows this model, with the women in the film's second half avenging Stuntman Mike's victims, and implicitly, the whole female gender.
