Following a pair of dystopian science-fiction misfires ("In Time," "The Host"), writer-director Andrew Niccol is rebounding by returning to the socially-conscious dramas that put his name on the map with films such as "The Truman Show," "Gattaca," and "Lord of War." In the modern war drama "Good Kill," the 50-year-old filmmaker reunites with star Ethan Hawke for the timely story about a morally-plagued drone operator balancing the war on terror with his suburban family.
