A stark and powerful mystery thriller, with a mood of deep melancholy that stuck with me long after I’ve left the theatre. Part of it is the natural setting, the vast, silent wintry expanses of snow and forbidding mountains of Wyoming, where the story takes place. While beautiful in its own way, this desolate environment makes for a harsh life. Another part is the sorrow and desperation of the people who live on the edge of this wilderness, and the hard-hitting, ugly violence of some key scenes. And there’s the haunting, sparse score from Nick Cave and Warren Ellis.
