This movie is not for connoisseurs of action or entertainment. It's a record of the pogrom unleashed in America on its citizens, in the name of purging communists, by Senator McCarthy. Clearly Oppenheimer was a tortured man, having given birth to the deadliest weapon known to mankind. The world is a better place because of it, as both Nazis and Russians were closer. However, other characters were not as well fleshed out, as expected with an ensemble cast. Robert Downey Jr as Strauss, was a revelation. Technically, it was well fleshed out. Nuclear science is complex. Kudos. Set design was outstanding. One actually felt dry and parched, seeing the setup in Los Alamos. Now I know who Dr Lawrence Livermore, was.
