Revisionist westerns are a subgenre of Western films that challenge the traditional narratives and conventions of the classic Western genre. These films often depict more complex characters, moral ambiguity, and a critical view of themes such as heroism, violence, and the mythology surrounding the American West. By reexamining historical events and cultural stereotypes, revisionist westerns highlight the darker aspects of frontier life, reflecting a shift in societal values and the evolution of the genre over time.
