Those who've given this movie a 1-star rating, claiming that the movie is slow or boring, lack either the class or the intelligence to comprehend and appreciate this work of art.
An absolute masterpiece, this movie beautifully illustrates the efforts put into the making of the atomic bomb along with strifes faced by those involved and the battle of morality that went on in people's minds regarding the need and usage of it. One can clearly see the extent to which research has been done to give the most accurate portrayals to character behaviours and looks. The movie wonderfully depicts the emotions that Robert Oppenheimer was going through and the sharp contrast in his behaviour before and after the bomb was deployed. A dilemma arising out of a dire need to do what must be done, and the repercussions and misfortunes that follow. Truly amazing!
