Christopher Nolan's Oppenheimer is a visual and audio masterpiece that follows the actual (to an extent) twists and turns of J. Robert Oppenheimer's (Cillian Murphy) tragic life as he headed the Manhattan Project, created the atom bomb and battled against a bitter Lewis Strauss (Robert Downey Jr.). The film not only takes moviegoers on a three-hour-long political thrill ride that any fan of historical non-fiction will appreciate, but it's also an ode to the times. For instance, aside from conveying the details of Oppenheimer's personal history, it also reflects the ideas, concerns and sentimentality of those who lived before and after World War II.
