The original script, completed on January 14, 1994, contained five sections: "A Fight to the Finish," depicting the last year of World War II; "The Decision to Drop the Bomb," raising questions about the need to use nuclear weapons against Japan; "The World's First Atomic Strike Force," illuminating the experiences of the bomber pilots; "Cities at War" describing ground zero; and "The Legacy of Hiroshima and Nagasaki," discussing the beginning of the arms race and the Cold War. In all, the script was over 300 pages.
It seems like the original script was actually fairly balanced and nuanced, covering the facts and decisions leading up to the event.
