For your consideration, one minute and forty-eight seconds that defines and expands an already fine and entertaining film, which makes it more, which makes it great. Here is the moment that tells us that, for all the cool dialogue, stylized violence and mayhem, and disjointed timelines, Quentin Tarantino has something on his mind.
This monologue is the heart and soul of the movie. Jules (Samuel L. Jackson, never better) and Vincent (John Travolta, never better) have just survived a point-blank encounter with a loaded Magnum, and a very close legal call involving a dead body. Jules thinks it's a miracle that they are even eating breakfast; he's quitting the life. Vincent thinks its just one of those things that happen, and that Jules is a fool and a bum. But we've already seen Vincent go down in a hail of bullets. It's going to happen in a week or so. Jules won't be there; he's taken off already.
What do you do with a second chance? What do you do with a third? The man who kills Vincent is a boxer named Butch (Bruce Willis, never better), who is given a second chance by saving Vincent's boss Marcellus (Ving Rames, never beter), who happens to be the man who is trying to kill him. Tonight, after leaving this diner scene, Vincent will have another miraculous close call, this one involving a syringe of adrenoline and his boss' ODing wife (Uma Thurman, better in Kill Bill). We've already seen that unfold too.
Other film-makers who ape Tarnantino's style miss that, for all his genre conventions, he makes his movies about something. The fractured timeline isn't there as a trick, it's not just to make it 'cool'. It exists to show you information you need to understand why this scene is the climax of the movie.
If you watch close you can see it; Pulp Fiction is a movie about a religious conversion. It is a man coming face to face with who he is, and realizing that nothing can ever be the same again.
