Burdened by the narration of the main character from beginning to end, with very little relief throughout, this movie feels like it never really gains the momentum it consistently builds up with. Despite the raucous trailer, this is NOT an action or thriller. It's a dark drama, very well written but more in the manner of a book than a movie. That said, there are still some disturbingly captivating scenes, and some great performances, namely by Essie Davis, Orlando Schwerdt, Nicholas Hoult, and especially George MacKay. While much smaller roles, Charlie Hunnam and Russell Crowe nonetheless delivered. Even with these in mind, the nauseating and babbling "climax" kept my 6 from leaping to a 7; it almost threatened to cut it down to a 5, the last half hour was that bad.
