This Chilean Western is excellent. Only 97 minutes.
It really shows the colonization and pillaging of the indigenous Chilean people.
There are no easy answers either. This is also the first movie I've seen in a minute where the violence isn't stylized and shown matter-of-factly. The same goes for rape. I've noticed Hollywood has a way of (sadly) showing rape in a sexualized way.
I highly recommend checking this out when it drops.
