Though the show was hush-hush during filming and production, the word is out, and CBS’s “Kid Nation” could be a big reality hit. It’s unclear when the show will air (probably in the fall) or what it will be called (probably “Kid Nation”), but one thing is certain: it’s a reality show that features nothing but kids. They’ll range in ages from 8 to 15, and have the task of creating (and running) an authority-figure-free society. It’s either going to be sheer chaos, network success, or both. CBS is undoubtedly hoping for both.
