Why is character development significant in narrative films?

Character development is significant in narrative films because it creates relatable protagonists and drives emotional engagement. A well-developed character allows audiences to connect on a personal level, as viewers can see aspects of their own lives, struggles, and emotions reflected in the character's journey. This connection fosters empathy and investment in the story, making the viewing experience more impactful.

Through character arcs, filmmakers can showcase growth, transformation, or challenges, which enhances the emotional stakes of the narrative. When audiences care about characters, they become more engaged with the plot and outcomes, thereby enhancing the film's overall effectiveness in conveying its themes and messages. The richness of characters also provides depth to the story, encouraging viewers to think critically about their motivations and relationships with one another.

The other options do not capture the essence of why character development is key to storytelling in films. Financial success, runtime, and plot simplification do not fundamentally address the emotional and relational aspects that character development brings to a narrative.
