The gripping tale of the father of atomic bomb where Cillian played Oppenheimer was one in a lifetime piece of art. The very nature of Nolan to keep you hooked to the screen until the very last moment is what so fascinating about him and that too in a 3 hour long cinema where you are constantly pulled to keep up with the facts as well as vicissitudes of the world war scenarios and then constant tension of Lewis Strauss(played by RDJ is also one of the best act of his career) about his image and authority challenged by Oppenheimer himself makes the story more deep and worthy to watch....Everyone should watch this piece of brilliant art irrespective of what others have to point out or say
