i found that the lack of time reference during the movie made it difficult to follow him thru his power gain and his fall. I mean there isint a peak moment and the audience doesn't get full "holy shit" effect out of the movie. How much would he import or process per month/week... how much money he made.
At the end i dig that between 1969 and 1976 he made 250Million+ plus but didnt get that effect during the actual story telling.
