Ahead of its premiere, the show proved to be the most controversial of the upcoming fall 2007 season, even though the only actual footage seen was a four-minute promo running on television and the Web. In previewing the series, CBS eschewed television critics, instead holding screenings at schools in at least seven large cities. Variety columnist Brian Lowry wrote that "Kid Nation is only the latest program to use kids as fodder for fun and profit, which doesn't make the trend any less disturbing." William Coleman, a professor of pediatrics at the University of North Carolina, argued that the younger children, ages 8 to 12, might not be able to deal with the stress, yet could be enticed to participate by the potential fame or be pressured to do so by a parent.Speaking before an audience of television reviewers, producer Tom Forman acknowledged that Kid Nation would inevitably share some elements with William Golding's novel Lord of the Flies, which depicted planewrecked children without adult supervision. But adults were present off-camera during the Kid Nation production, including cameramen, producers, a medic, and a child psychologist, although all interacted with the children as little as possible. Participants also missed a month of school, but Forman suggested that such real-world tasks as preparing a group breakfast, doing physical chores like fetching water, and making group decisions constituted an educational experience in its own right. Foreman said that all participants were cleared by a team of psychologists, any child could choose to go home, and some did.Los Angeles Times reporter Maria Elena Fernandez interviewed four of the children, who told her they had worked harder than they ever had in their lives but would willingly repeat the experience. They said the most challenging aspect was getting used to being filmed constantly.
