Sometimes "Bravo" serves-up high-quality instruction at least as powerfully as "The Learning Channel" and "National Geographic." Case in point: "Kell on Earth" reveals the ecology of New York's fashion industry, vividly illustrating the perilous lives of smaller fish on the couture food chain, and charting the symbiosis between design houses and the fashion press. The "Kell" in "Kell on Earth" refers to hyper-manic high-powered fashion publicist Kelly Cutrone, diva-dominatrix of public relations firm "People's Revolution." Although eponymous Kell gets the most air-time, "Kell on Earth" is not automatically all about her; instead, it shows the harried lives of second-tier stylists, public relations interns, and personal trainers who dwell near the bottom of New York's tumultuous, tempest-tossed fashion fishbowl. Observant viewers will note striking similarity between People's Revolution and Lauren Conrad's workplace on "The Hills" and "The City," which brought Cutrone into the public eye. Those same insightful viewers will see, however, that real-reality show "Kell on Earth" proves Cutrone's "little people" frequently sweat, swear, and stress, really working for their paychecks.
