From a Washington Post review by Ann Hornaday headlined “Christopher Nolan’s ‘Oppenheimer’ is a supersize masterpiece”:

“Oppenheimer,” Christopher Nolan’s masterful portrait of the man known as the father of the atomic bomb, has been anticipated with some skepticism among filmgoers who wonder how Nolan’s penchant for Imax cameras and thundering sound designs would serve a story that, at its core, amounts to scenes of different groups of men arguing in different kinds of rooms.
