Oppenheimer was a giant misopportunity. Matt Damon was miscast as General Groves. The guy who played Oppenheimer didn't impress me that much either. Better films that tell the story of the Manhattan Project are Day One, and Fat Man and Little Boy. Oppenheimer is overrated and was not an Oscar worthy film. Anything that Nolan does is overrated. His Batman trilogy is his best work. He hasn't impressed since.
