No one would deny that Harper Lee's 1960 Pulitzer-winning novel, about Southern racism and doing the right thing, is a major work of American literature, or that its instant canonization was eventually a curse to its author. Mary Murphy's doc also takes these truths to be self-evident---and then continues to reiterate them ad infinitum, in the absence of finding anything truly revelatory about the writer's prepublishing history or postcelebrity reclusiveness. Famous fans (Rosanne Cash! Oprah!!!) attest to the book and film's greatness, but at best, this is a half-hour A&E Biography episode padded out to feature-length with forgetful trivia, frustratingly facile history lessons and far too much fawning.
