It has already become a classic film from 36 years ago, Dances with Wolves (1990) is an epic work that deeply explores the lost human nature, nature itself, and the understanding between different cultures.

At the center of it is the story of the Sioux tribe, particularly the Lakota, who actually lived in the South Dakota region.

The protagonist, Lieutenant John J. Dunbar (Kevin Costner), is injured in the Civil War and, prepared for death, goes to the front lines, only to miraculously survive. He chooses a life disconnected from the world and volunteers for a remote outpost in the West. There, he first encounters the harsh and lonely nature, and the Lakota people who have maintained their own order and culture within it.

Initially, they are wary and misunderstand each other, but as time passes, Dunbar realizes that they are not mere "savages," but a wise people living in harmony with nature and as a community.

Dunbar goes hunting with the Lakota, learns their language, and immerses himself in their daily life. Before long, he feels a greater sense of peace and humanity within their community than in the civilized world he came from.

The Lakota give him the name 'Dances with Wolves,' which signifies that he is an outsider with an open heart trying to understand their world.

The true emotion of this film lies in the perspective of the Lakota. Previous Western films often depicted Indians as primitive or violent beings, but Dances with Wolves attempted a different approach.

Kevin Costner respects their culture, language, familial love, and sense of community, moving away from a white-centric view to show a 'human to human' relationship. Notably, a significant portion of the film is conducted in the Lakota language, and Lakota actors participated, adding authenticity and realism. Through this, the audience comes to feel that Indians are not strange beings but humans who love, fear, and grieve just like everyone else.

Dunbar falls in love with a white woman living with the Lakota, 'Stands with a Fist,' and as he learns their culture while living with the tribe, it becomes a transformation of identity rather than just a romance.

He no longer exists as a soldier or a white man, but simply as a human being. Ironically, however, civilized society cannot accept him, and Dunbar is once again pursued by the military to protect the Lakota. This ending illustrates the paradox that human desire disrupts harmony with nature, and civilization loses its humanity.

The essence of the film's emotion is 'understanding and respect.' Dunbar escapes from a world dominated by guns and rules, learning the true meaning of peace and community through the Lakota. The film's true message is the attitude of seeking learning within differences rather than fearing them. Additionally, his journey to restore the relationship between nature and humanity revives the innate emotions of humanity that are forgotten in today's environmental destruction and civilization-centered values.

The life of the Lakota in the film is not just a depiction of past indigenous life but serves as a mirror questioning how humans should live within nature. They respected life even when hunting buffalo and regarded the stars, wind, and earth as sacred beings. As Dunbar spends more time with them, the process of reviving the emotions of humility, solidarity, and gratitude that civilized people have lost resonates deeply with the audience.

Ultimately, Dances with Wolves restores the story of the indigenous people trampled under the name of westward expansion through the eyes of a white soldier, questioning the relationship between humanity and nature once again. The essence of that emotion is not merely friendship or love, but the 'true peace' that exists only when different worlds can genuinely understand each other. I believe that in the moment Dunbar and the Lakota danced together on the vast plains of South Dakota, the film revived the beauty of harmony that humanity had forgotten.
