Not a story I was aware of. Well acted, probably cut down a bit for time like most films. The key characters are reasonably well explained, perhaps one fringe character isn't, but they are being used for effect. It's done well, but moves fast towards the finish....which makes sense considering the mental health of the main character.....it doesn't dwell on the stuff that is thrown in to pad it out. Also I like that it doesn't create overly sympathetic characters, nor monsters. It's not a faithful to every detail biopic, it's going for a feeling of what happened and possibly why it happened
