When I saw the movie Behind The Candelabra I was disappointed that it was mainly about Liberace's bizarre sex life with nothing about his relations with family members such as brother George and others or about his early life. In Rebel In The Rye it was all about J D's life from taking writing classes to the success of his novel and life after that but we only saw son Matt as a baby (or was that J D's daughter?) so nothing about their father-son relationship.
