Is western movies the least flexible genre?

Western movies are not necessarily the least flexible genre. While they may have certain conventions and tropes that are often followed, there is still room for creativity and innovation within the genre. For example, some Western movies may incorporate elements of other genres, such as comedy, drama, or horror, to create a unique and engaging experience for viewers. Additionally, Westerns can be set in different time periods and locations, allowing filmmakers to explore a variety of themes and stories.
