To analyze a nation's social mood through films, examine themes, narratives, and character portrayals in popular movies. Focus on recurring motifs, such as optimism or despair, and how they reflect societal values or anxieties. Study genres, visual styles, and dialogues for cultural cues. Box office trends and audience reception can reveal public resonance. Cross-reference with historical and social contexts for deeper insights. For example, dystopian films may signal collective fears, while comedies might reflect resilience. Use film databases like IMDb for data on trends and reviews [https://www.imdb.com].
