Writer/director Martin McDonagh has a special knack for behavioral insight, and the man loves his dark comedy. With “In Bruges” and “Seven Psychopaths,” McDonagh was cautious but somewhat glib with his characterizations, threatening quirk and a disruption of tonality. With “Three Billboards Outside Ebbing, Missouri,” McDonagh finds a stunning cohesion between mischief and soul-splitting grief, putting the pieces of this puzzle together with flashes of violence. It’s a magnificent film, with McDonagh almost wizard-like in his ability to surprise with recognizable working parts, creating a powerful and intricate character study that finds tremendous value in the inner workings of damaged people. It always threatens to spin out of control, but McDonagh secures a buzzing atmosphere of threat to the effort, allowing “Three Billboards” to blossom in unexpected ways, and it possesses a few glorious sucker punches to keep viewers from becoming too comfortable.
