I have watched Boyhood probably three times, most recently just a few weeks ago. Not many films speak to my whole family like that one does (my wife, my daughter and I). As an added bonus we're Beatles fans, so we loved the concept of "The Black Album"! The three of us also were touched separately and later together by Harold and Maude. That film still sticks with me all these years later. Ignoring convention to live your life on your own terms and find happiness is what it said to me.
So many novels have moved me during my life. Most are cliches at this point. The Catcher In The Rye, On The Road, Atlas Shrugged, all moved me and changed me at different times for different reasons. Richard Russo novels always refresh and renew me to this day.
