If, as the saying goes, humor can be a great revealer of and conduit into hard, unspoken truths, then surely a parallel axiom could also be valid — that a humorist might be able to provide an important and clarifying look at heretofore muddied and jumbled realities. Such a hypothesis is born out in the form of Harry Shearer’s feature documentary debut, The Big Uneasy. A look at the true root causes of the Hurricane Katrina disaster in New Orleans, the movie, while a bit pedantic, nonetheless stands as an important correlative primary historical document, alongside Spike Lee’s When the Levees Broke: A Requiem in Four Acts and If God Is Willing and Da Creek Don’t Rise.
