In "Blues Ain't No Mockin Bird," Granny resents the filmmakers and cameraman for several reasons, and they are all good and right reasons. First, after asking if they could film her and her family as part of a documentary and being told "No," they continued to try to cajole and persuade her against her wishes. This is highly disrespectful.
Second, they continued to affront her by remaining on her property, property that she and Granddaddy owned. Third, they insisted on filming against her express wishes and after clearly have permission denied. This all gives Granny sound moral and legal reason to resent the intrusion of the filmmakers and cameraman on her property and in her family's life.
