Final answer:
The film's mood is uplifting, influenced by the change in music from soft and sad to high, bright, and bouncy notes, which correlates with a positive emotional shift in the scene.
Step-by-step explanation:
The mood of a film can be greatly influenced by elements such as lighting, music, and narration. In the scenarios described, where the protagonist sees a man walking toward her while the music swells to high, bright, and bouncy notes, the mood can be described as uplifting. This is because the music evokes a feeling of happiness and a positive change in emotion from the previous sad and grim expression on the woman's face.
