I'm a huge Tarantino fan, and Pulp Fiction is my favorite movie of all-time. And after watching it a ton, I've noticed a lot of things that I never really hear film critics talk about. Generally, when I read essays on Pulp Fiction, critics get caught up on all the movie references, and they also seem to struggle with analyzing the film as a single work, since the movie appears so disjointed with its multiple storylines. But I think I've recognized some larger themes that are relevant to all of the chapters, as well as the prologue and epilogue in the Hawthorne Grill. And after looking at how every major scene in the film fits in with these larger themes, I've found that that Pulp Fiction is as focused and tightly crafted a film as any I've ever seen. And I've seen my fair share.
I've written an essay of my own that explores these themes, and uses them to uncover the meaning behind some of the more ambiguous scenes in the film (although I still have no idea what's in the briefcase, unfortunately). I think the stuff I've come up with also reveals the significance of a lot of minor details, like the songs chosen for the soundtrack, and the TV shows that the characters watch.
As for what those themes are, they revolve around the concepts of love and hate, as well as the place these concepts hold within the alternate universe that the film takes place in. I've accumulated a massive amount of evidence to support this assertion, and I hope that you get a chance to look at what I have to say. Here's the link to the Pulp Fiction essay I posted on my personal website:
To sum up my essay, every storyline in Pulp Fiction involves love (Mia, Fabienne, Bonnie, and Honey Bunny are all love interests), and every storyline involves violent people (with violence being an act of hatred). Good things invariably happen to characters who embrace love and shun violence, while bad things invariably happen to people who reject love and continue to harm others. Moreoever, Ezekiel 25:17 actually says that God will reward good people, and punish the wicked. Now, I'm not a religious person myself, but that doesn't mean he doesn't exist in the world of the film. Here's an excerpt from my essay that explains why:
After all, whether or not you believe God exists, you must acknowledge that every work of art has at least one Creator. Our universe may have come about through natural means; but there can be no paintings without painters, no books without authors, and most important of all to our discussion on Pulp Fiction, no films without filmmakers. Who knows if there is a God, but everyone knows there is a Tarantino.
If the summary of my essay interests you, just know that my actual essay proves all of it! There's a lot of good stuff in there, and hopefully you'll have time to read it. Let me know what you think of these ideas!
