content: This is truly a bad movie....The historical "premise" is incorrect. JFK expanded the war in Vietnam, and there is no reason to believe that he would have changed his mind if he had not been assasinated. The conspiracy plot is laughable. I did not think it was possible for me to feel sympathy for Lyndon Johnson, a failure as President, but the movie almost invoked those feelings by portraying him as a conspirator against JFK. Kevin Costner is awful as Garrison. His accent is amateurish, for example. Tommy Lee Jones is the only actor who puts in a credible performance.
