The way it presents the story might be different. It could use a particular narrative style that combines elements of mystery and authenticity. Maybe it weaves together different voices from within the story, like the perspectives of leaders and ordinary members. This can create a more complex and engaging true - story experience compared to others that might have a more straightforward linear narrative.
One aspect that could make it unique is its focus. If it's about a relatively unknown or niche group or event, that sets it apart. For example, if it tells the story of a small, isolated community's way of life under a specific religious or cultural 'banner of heaven', it offers a perspective not often explored.
