a biography; not a documentary I expected this film to add to and expand upon "Fat Man and Little Boy" (a MUCH better film). This flik's focus is on the man, his foibles an his eventual betrayal and castigation by the US government. At 3+ hours, it's quite a bit overdone.
If not for leading the Manhattan Project, Oppenheimer, the person, would merely be a footnote in high energy psychics.
Until the last third of the movie, there is little offered to give sympathy to him. By that time, sadly, he becomes a virtual and physical shell of himself.
The film spent more celluloid on his detractors and competitors and did not offer an equal comparison with his proponents.
Needless to say, I would not recommend. Watch Fat Man instead.
