Thank you. We just watched the movie as a family - the first time for my 18 year old. He took the book from our shelves and began to read it.
He was deeply moved by the character of Atticus, but most of all by the relationship between Bo Raddley and Scout. There are too many young people who are more than happy to throw rocks at the perceived weird or odd ones - from the streets of a city, to the halls of a high school or college, to an on-line chat board.
This movie helped him to understand just what you lose of *yourself* by doing that. Essentially that is the moral of the trial, as well.
Fictional plots and psychologically-recognizable characters are the way that we can most effectively share our own narratives of the way life works. Harper Lee was speaking for all Americans when she argued that we must base our narratives on common themes - just as the Constitution - but we have to be brave enough to remember that group rules may not be good ones after all. We must keep our values articulated and clear.
'Group think' isn't always right, nor is it always moral. Consider the attitudes of folks about abortion nowadays. Many accept it because it's 'legal', confusing legal with moral, and they don't want to appear unsophisticated by the 'group', for going against them on the issue.
