Sounds like the lib Pitt infused his politics into the movie, just as FSF did in much of his writing. Was there ever a worse ending and soapbox than the ending of This Side of Paradise when the hitchhiker proclaims his socialism to the wealthy guy who gives him a ride?. Though I've read all of FSF’s writings, I won't be reading them again looking for greater depth as I have with truly great literature, which continually ‘feeds’ me as I return to it every 5 or 10 years.
FSF and Pitt, to me, are both way overrated.
