To begin with, as others have pointed out, Harper Lee did not write this. Secondly the story line is ridiculous with Durham, NC being portrayed as a hick town. Think about it, Durham North Carolina is home to Duke University, one of the most respected universities in the world, and Duke Hospital, a leading research center and medical treatment facility.
Durham is thriving and part of the Research Triangle, consisting of Raleigh, Durham and Chapel Hill. The residents are not "close knit" and Durham is not a "crumbling community" but this movie is a dull pointless mess.
I got about a third of the way through and turned it off.
