Apparently Willy Staley of the New York Times missed all the satire in KotH. Someone in the critical analysis business who understood towns like Garland, TX well wouldn't dismiss the satire in KotH offhand. Shows can be relatable and funny and still be misunderstood.

And I don't think cities necessarily corrupt people somehow. Obviously Garland itself is part of the DFW metroplex! It's probably more that people with a certain brand of cosmopolitan ethnocentrism end up in (or stay in) coastal cities.
