My god, what a movie! I saw Neils Bohr and went wooh!, while everyone was staring at me. All the big names—Einstein, Feynman, Slizard, Fermi, Bethe, Teller, Lawrence, etc.—were portrayed, and I was looking around for people's reactions. The point is, the movie is not for everyone; stuff is not spoon-fed; you've got to know your history and science to understand some parts. The movie is long but does not feel like it, and yeah, the explosion scene is the best bombing scene ever from Hollywood.
