He makes an impact on the Finches and shocks the other characters by his act of bravery. Being completely shut off from the world at such a young age forced him into an antisocial and awkward kind of person. Robert Duvall (actor who portrayed Boo) made sure that point came across. When put to the test, Boo willingly came out of his shell and rescued Scout and Jem. His true colors shined through when he saw them in a life threatening situation, and that’s what makes him unique.
To Kill A Mockingbird is a priceless and classic piece of American literature because it emphasizes symbolic changes that we as a country went through. Even though Atticus, Miss Maudie, Jem, Scout and Boo all grew up in a world full of hatred and racism, they overcame it by being respectful, influential, and courageous. It reminds us of how far we’ve come from the harsh past and helps us appreciate our freedom more.
