Pulp Fiction can be considered a postmodern film for several reasons:
1) It has a non-linear narrative structure that is split into three separate stories and requires the viewer to pay attention to piece together the timeline of events.
2) It incorporates intertextuality by including references to other works, such as characters quoting from the Bible or hairstyles mirroring those in other films.
3) It flattens effects by juxtaposing casual discussions of drugs, crime, and sex with normal conversations, which decreases the dramatic effect and deviates from film norms.
