Quoting the article:
Anderson would be the last person to gloss over the severe problems of the urban poor, but in The Wire he sees “a bottom-line cynicism†that is at odds with his own perception of real life. “The show is very good,†he says. “It resonates. It is powerful in its depiction of the codes of the streets, but it is an exaggeration. I get frustrated watching it, because it gives such a powerful appearance of reality, but it always seems to leave something important out. What they have left out are the decent people. Even in the worst drug-infested projects, there are many, many God-fearing, churchgoing, brave people who set themselves against the gangs and the addicts, often with remarkable heroism.â€
Hmmm. Not quite sure what Professor Anderson is saying here or whether we’re watching the same show. Those individuals are ably and amply represented throughout the show, from Randi’s step-mother to the recurring Steve Earle character; none of these characters are pure but they shouldn’t be. Furthermore, the good intentions of various characters, some of whom have “set themselves against the gangs and the addicts,” often misfire when the dysfunction of urban institutions leaves individuals helpless before neighborhood decay.
