Well, it might be that this person has a very warped view of the world. They could be lumping dogs together with something they consider 'filthy' in the context of a type of writing like 'pulp fiction' perhaps because they see dogs as common or unrefined in some strange way. But it's really not a fair or accurate view of dogs at all.
Maybe they love the movie so much that they want to hear again whatever was said about it. For instance, if it was a trivia fact.
I'm not entirely sure what it specifically means. 'Filthy' is a very unkind description for dogs which are generally clean animals. And 'pulp fiction' is a type of writing, so it's really hard to make sense of it as it is. It might be a very personal or creative, yet inappropriate view of dogs.
Perhaps they are really into the style and themes of 'Pulp Fiction' and see a relationship or connection in it that they feel strongly about, so they express it this way.
It could be that there was a business deal or a creative collaboration related to 'Pulp Fiction'. But in hindsight, it turned out to be a bad idea. So the person is saying that from the start, one should have said no. Like if it involved investing in a 'Pulp Fiction' - themed product that ended up failing in the market.
It could be because 'Pulp Fiction' is a very influential piece of work. It has influenced a lot of other movies and books in terms of style, story - telling and character development. So the person saying this might believe that everyone can learn from it or enjoy its unique qualities.
Because it's a great movie. Simple as that.
Maybe it was in response to a revelation about the movie's characters. For instance, if someone finally pointed out a simple but crucial fact about a character's motivation, another might say this.
In Pulp Fiction, pigs are not really the focus in terms of being filthy. However, in general, pigs might be wrongly considered filthy because they roll in mud. But this is actually a natural behavior for them to cool down and protect their skin from the sun and parasites. In the context of the movie, it could be just a passing comment or an expression of someone's view that doesn't necessarily have a deep - seated meaning related to the overall plot.
Well, in 'Pulp Fiction', it might be that the idea of a pig being a filthy animal is part of the overall gritty and somewhat unseemly world that the movie portrays. Pigs are often associated with messiness and gluttony in general cultural perception. The movie might be using this common perception to enhance the atmosphere of the story, to show the base or unrefined aspects of the characters or the situations they are in.
They might say it because they think there's too much of it. The market could be flooded with science fiction books, movies, and shows, and they feel it's time for something new.
