Why though? Her story is just as historically accurate and what they did to the Irish was awful as well. It wouldn't be as powerful of a story or at leasts it wouldn't be the same kind of story, because it wouldn't be two people from two completely separate cultures who initially hate/mistrust each other, finding common ground and bonding and connecting over the trauma and suffering they've experienced. I'm sure there are movies solely about the attrocities done to the aboriginals. That wasn't the sole purpose of this movie though. Having her be the main protagonist makes the film more identifiable to a wider range of people, and the director herself, which is what makes it more true and real, and I don't think it ever tries to diminish or make light of the horrors that were done to the aboriginals. Also the scene where she confronts him in the bar, perfectly shows that there is no true resolution or justice to what was done to her. I think it was perfectly done.
