I feel like I'm being a little generous with the 2 stars because I really want to like this and it was well produced.
I shall also confess to not being recently well conversed with the lore, but I remember the vagaries reasonably well.
The characters and motivations, I think can easily be summarized by the struggle for good and evil being: White person bad, dark skinned/ethnic minority person good.
I don't quite recall from the games if Helena is meant to be of Aboriginal descent, but here she's presented as having found her roots in personal strength from her mother taking her, a child, to an aggressive rally espousing aggressive signs about land ownership (which I might add are not remotely in keeping with Aboriginal spiritual ideas about being custodians, not owners, of the land).
In that formative scene, we get the heart of the message quickly.
For apparently no reason, at this rally, the white people charge and attack the Aboriginal people.
Mind you, none of them seem surprised and yet her mother still took her. Bizarre writing...
Then there's the morphing of Rockwell from the good man he was meant to be into a total worm from the onset.
His character journey was one of the descent into madness, not starting from it.
