I was expecting there to be more about the development of the bombs. One thing I was certain was going to be in the movie, for example, was not even mentioned: tickling the dragon's tail. That is the sort of content I was hoping for in this movie. If you are not familiar with this, do a search for Slotin, Daghlian, and tickling the dragon's tail. Essentially, what Slotin did was to carefully move two hemispheres of nuclear material ever so slightly closer together in an attempt to see what happens just before criticality. Oops! Yeah, major oops. I suppose these things weren't include because they actually happened after Hiroshima and Nagasaki by which time the movie was mostly over. That's fair, I guess. Still, that is the type of thing I was hoping for.

Instead, what was shown was basically a soap opera. And the music was annoying. Music is masterfully done in such movies as the Star Wars movies, where the music plays a large role in the production value of the film. Here, though, it's mostly used to fill dead air. Almost all dialog in the movie is nearly overwhelmed by meaningless music. I think the movie would have been far better with at least half the music removed entirely. Let us hear what people are actually saying.

I can't fault the acting. It was superb.
