Well, one similarity could be their unique storytelling styles. 'Steel Ball Run' has a very complex and engaging plot in the manga world, while 'Pulp Fiction' is known for its non - linear narrative in the movie realm. They both manage to keep the audience on their toes with unexpected twists and turns.
The theme of survival is present in both. In 'Steel Ball Run', the characters are in a dangerous race where they have to fight for their lives and achieve their goals. In 'Pulp Fiction', the characters are also in a world full of danger, whether it's the hitmen dealing with their jobs or other characters facing various threats.
The JoJo manga is mainly in black and white. Colored versions exist but are not the norm. Sometimes, colored illustrations are done for promotional purposes or by fans.
