"Don Draper is consistently true to the past the writers have established for him. Some critics find his appealing unflappability implausible, and they fault the show for sacrificing its commitment to verisimilitude in the interest of maintaining the lead actor’s appeal. They fail to grasp that Don--whose entire identity is a fabrication--would have to possess preternatural cool. He’s always on."
