Filmmaker Davis Guggenheim reminds us that education statistics have names: Anthony, Francisco, Bianca, Daisy, and Emily, whose stories make up the engrossing foundation of the big screen documentary, “Waiting For Superman.” As he follows a handful of promising kids through a system that inhibits, rather than encourages, academic growth, Guggenheim undertakes an exhaustive review of public education, surveying drop-out factories and academic sinkholes, methodically dissecting the system and its seemingly intractable problems.
