The Bush that comes out of Stone's film is a fair representation of the real thing: a rather foolish man, eventually (under the influence of God) motivated by the right considerations, but whose many weaknesses of character cause him to make some bad choices of colleagues, and then to allow them to dominate him and use his term of office as an experiment in a new world order.
There is no mention of all the domestic disasters over which the Bush Administration has presided, and which has left its economy the swamp of a disease that has since infected the rest of the world: but then there doesn't need to be. The charge sheet is long enough as it is.
In some ways, the Bush story is a conventional one, and Stone plays it reasonably straight.
The combination of a life of privilege, birth into a dynasty of politicians, an intimidatingly successful father, the ready availability of money, no apparent need to work for a living and a sense of entitlement about political power were the beginning of the corruption of George W. Bush.
He is depicted as having been unemployable save for his father's contacts and his father's money opening doors for him. He could stick at nothing and became a drunk before being born again into Christianity.
With little grasp of any political issue, he was smuggled into politics. With some pretty odd traits of character, he became President, almost by accident.
That defective character drove him to make key appointments from among men who served his father: but then his father was a war hero, an experienced politician, a man of authority. Men who had served him now conspired to make his son serve them.
