The film rambled on and on without any respite. There was high drama, and it's a good documentary but not a good movie. Ultimately, it turned again into an explanation and clarification we don't need anymore. Nolan still used half-truths and myths about a scientific endeavor that would have happened any day. At many points, the film became a visual and emotional whip. What Oppenheimer did or didn't, hardly matters now. Let's see atomic energy as a source of energy and stop pinning it on a war that was also the genesis of many first-time inventions. America's stance on the Worl War created a lot of contention, let's not prod it anymore.
