Review by Manhola Dargis : 'For all the silly walks and comic cameos, anger fuels "The Informant!," giving it its pulse and reason for being. Anger inspires its giggles, forces its tears and might even explain the fiery orange that colors so many faces, as if this world and its people were on the verge of immolation.'
Review by A.O. Scott : 'like "No Country for Old Men" and "Burn After Reading," fundamentally a shaggy dog story. But while it is funnier than either of those movies, it also has more gravity to it. This is not just because it represents something of a homecoming for the brothers, who grew up in the heavily Jewish Minneapolis suburb of St. Louis Park in the 1960s. They are hardly the kind to be sentimental about the old neighborhood. But in that milieu their smart-alecky nihilism feels authentic rather than arch ? you understand, maybe for the first time, where they are coming from.'
