Deal and Lessin's documentary isn't an anatomy of the so-called Kochtopus, nor is it a study of the Koch's business empire. A better title for this documentary might be "Scenes from the Class Struggle in Wisconsin."
"Citizen Koch" is preaching to the choir. Which might not be a pointless exercise, seeing how the choir failed to show up for the last midterm election in 2010, and might need extra motivation not to repeat that mistake this November.
The documentary "Citizen Koch" is uneven and scattershot at times, but when you're target is as big and fat as corporate money in politics, you can afford to be a little scattersot and still hit your mark.
The inescapable conclusion from the film is that there is something even more distressing than the impact of near-unfathomable individual wealth on politics: the impact on public understanding of the issues.
