I think Sam Waterson in the 1990s TV series did a better job portraying Oppenheimer. I found the long cinematic pauses for Oppenheimer introspection annoying. Mat Damon did an excellent job portraying Groves. The other movies on Oppenheimer and the Manhattan Project also have strong and weak points. Fatman and Little Boy is the only one who showed how dangerous the work was with its composite portrayal of the “Tickling the Dragon’s Tail” incident.
That movie was more about the project then Oppenheimer as was Day One.
My overall assessment of Oppenheimer was good but for me the psychological angst parts over and over was irritating. However that’s my tastes in movies others may see it differently.
I am early in the book American Prometheus, the story of Oppenheimer. So far the movie follow the book fairly well. Oppenheimer was a flawed character of somewhat a lot of that probably due to his early life and the atmosphere in school that he was exposed to. He came from a very wealthy Jewish family and went to a rather progressive school in New York, which probably led to his interest in many leftist causes. Most of these academics and theoretical physicist lived in a fairly insular world of academia. None of these people were ever truly exposed to the horrors and realities of what they thought they believed in.
