If you are going to the movie for nuke, or the nuke on Japan, then forget about it. This isn't your typical American action movie of big explosion or what not. This movie is about the journey of Oppenheimer. There is noting to be spoiled because you can read Oppenheimer's story up. I would go to the movie to enjoy how the top tier actors convey the story to you through a combination of different colored shots and sound mixes. What makes this movie extra trilling was the final hour, when the movie transition from showing the journey of a man to questioning whether mankind's pursuit of power is justified.
