When I think of the Coen brothers, I think of their movie Miller’s Crossing. More specifically, I think of the scene at the end of Miller’s Crossing, when John Turturro begs Gabriel Byrne to “Look in your heart!” and Bryne replies, “What heart?” before shooting him. That, to me, is quintessential Coen: witty, achingly clever, and heartless. If there’s a line where unsentimental becomes schadenfreude, every Coen brothers movie ignores the delineation. Their new effort – A Serious Man – is a comedy of torture. A nebbish physics professor asks the meaning of his existence, and the movie answers him the way Gabriel Byrne answered John Turturro.
