'Oppenheimer' review: Sympathy for the destroyer of worlds

At one point in Christopher Nolan's Oppenheimer, the father of the atomic bomb dons his iconic uniform — a fedora cap, a smoking pipe, a slightly over-sized suit — like Batman wearing his cape and cowl for the first time. It's a look that serves as a sort of armor against mere mortals, who he woos with a peculiar charisma, as well as the military and political bureaucracy he battles while leading the Manhattan Project. It's also a way for J. Robert Oppenheimer (played by Cillian Murphy) to ground himself as he wrestles with the major conflict around his work: Building an atomic bomb could help win the war, but at what cost to humanity?
