A mashup of 'Pulp Fiction' could be a creative combination. For example, it could be a musical mashup that combines the iconic soundtrack of 'Pulp Fiction' with other music genres. Maybe some DJ has blended the surf - rock and funk tunes from the movie with modern electronic beats to create a unique auditory experience.
One popular mashup fiction book is 'Pride and Prejudice and Zombies'. It combines the classic story of 'Pride and Prejudice' with the horror element of zombies, creating a unique and entertaining read. Another is 'Abraham Lincoln: Vampire Hunter', which mashes up historical facts about Lincoln with the fictional concept of vampire hunting.
Well, in an anime mashup novel, one key element is the blend of different anime universes. For example, characters from a shonen anime might interact with those from a magical girl anime. Another element is the plot which often has to be carefully crafted to make these different elements fit together. And the art style, even in written form, might be influenced by the distinct visual styles of the animes being mashed up.
In general, the Evangelion mangas are considered good. They expand on the anime's universe, providing more depth and character development. However, it depends on personal preferences as some might find the style or pacing not to their liking.
