Rain Man is Dustin Hoffman humping one note on a piano for two hours and eleven minutes. It’s his dream role. As the autistic savant Raymond Babbitt, he’s impenetrable: he doesn’t make eye contact or touch anyone or carry on a conversation; he doesn’t care what anybody thinks of him.
This movie has had the bad judgment to turn Robin Williams into a role model. Good Morning, Vietnam takes a real culture hero and turns him into a false one.
