I began to watch only because the director is famous, because the fate of the scientist did not particularly interest me.
If what has been told for three hours is true, Oppenheimer was a miserable man whose fate is beyond envy.
He, satisfying his scientific interest in physics at the expense of the state, came to the creation of the atomic bomb. So far, tests have not been carried out, but they assumed that this would be a formidable weapon that would lead to the cessation of wars on Earth. Its presence will contribute to peace on the planet.
But the test of the first sample showed that the bomb is many times greater than the expected effect of the explosion. Oppenheimer was horrified by what he saw at the trials. The tragedy of the situation was exacerbated by Hiroshima and Nagasaki a few days later.
Nolan perfectly showed the excitement of the scientist, his passion, and then a terrible depression. This is shown not only by Killian Murphy’s performance, but by the whole environment around him.
There's a second storyline. After the triumph of a successful test, Oppenheimer was organized merciless persecution. It was organized by his closest patron and, as he believed, a friend. He made personal scores with the scientist.
I watched for three hours without stopping. I was happy, because I expected a lot from Nolan, and I was not mistaken.
