It's well directed, the acting is more or less universally good: in particular William Hurt, who comes in near to the end. The story is largely mundane, interspersed with sudden explosive acts of sex and/or violence. The plot itself is rather dull, but the action is very good. I think the dullness or pointlessness is almost deliberate.
There is a philosophical underpinning to the film, about the role of male violence in simultaneously shoring up, and threatening, the family and our culture. I think there is a parallel being drawn with going away to war, and how we react to the soldier.
