Why Are flashbacks often necessary in stories with in media red openings?

Flashbacks are often used in stories with in media res openings as a way to provide context, background information, or character development to the audience. They help to fill in gaps in the narrative and enhance the viewer's understanding of the story by revealing key events or details that occurred before the main plot began. This technique can create intrigue, build suspense, and deepen the emotional impact of the story.
