The movie is perhaps too long, but I rate it way above average. At the age of four, I did not know of the project or that a bomb had been dropped till I was eight or so. The committee on Un American Activities has interested me and I recall hearing radio broadcasts of the hearings.
Seeing the movie in Imax was a real treat, my seat actually vibrated with the spectacular sound. Parts of the movie almost brought me to tears. The acting was great, without exception. I came home to look up more about Oppenheimer himself.
