These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Come Oscar time, Pulp Fiction was nominated for 7 Awards but only won for Best Screenplay (Original). It lost Best Picture to Forrest Gump and also was up against The Shawshank Redemption, and there's been debate over which movie deserved the Oscars ever since.
Subverted with the Cannes Festival, however, where it was awarded the Palme d'Or by a jury headed by Clint Eastwood, no less, to the shock of many film critics. This led to a hilariously awesome trailer starting with a deep, portentous announcer talking about how it's the winner of the Palme d'Or, before a pair of bullets interrupt him and the real trailer starts.
Unrelated to Forrest Gump, many would say that Samuel L. Jackson and Uma Thurman could've made very deserving winners in the supporting categories, yet they lost to Martin Landau (for Ed Wood) and Dianne Wiest (for Bullets Over Broadway), respectively. Certainly up to debate, though, especially in Jackson's case, as Landau — aside from being a film/TV veteran — was seen as giving a tour-de-force performance as Bela Legosi.
Everyone Is Jesus in Purgatory: How much divinity is involved in the film's events is a frequent matter of debate. Jules himself believes he was part of a Divine Intervention. A lot of people also like to argue about Marsellus Wallace, that he is the Anti Christ because he has a band-aid on the back of his head which is supposedly covering up a 666, which is also the number needed to open up his briefcase. And the question of what, exactly, is in that suitcase. One such suggestion? Marsellus Wallace's soul.

Memetic Mutation: The film spawned many memes that were especially popular in the 90's.
"What?" "English, motherfucker! Do you speak it!?"
to get medieval on something
"My (anything you want) is the one that says "Bad Motherfucker" on it."
(Christopher Walken imitation) "I hid this uncomfortable hunk of metal — up my ass..."
"This IS a tasty burger!"
"Say 'what' again!" This quote has recently become a popular image macro on the Internet of Jules wielding his gun with the caption "Say X again! I dare you! I double dare you, motherfucker!" Usually used to express annoyance at someone saying or doing something ad nauseam.
