I remember loving the book, especially the humour. For example: "There are three kinds of mathematicians, those who can count and those who can't." But the movie was (for me anyway), dour, preachy and depressing. A lot of hand wringing about the morality of working on the H-Bomb built into the dialog. No doubt some (or maybe many) of the scientists working on the Manhattan project were morally conflicted, but I doubt that they spent a lot of time while working discussing this as shown in the movie. I wish the movie had addressed this issue but had given more focus on Ulam's humour.
