From The Los Angeles Times Harper's Island article: "It's not as if the networks have an aversion to gut-wrenching fare. "CSI: Crime Scene Investigation" in all its forms regularly features horrifyingly defaced corpses, often sexualized (a key element of the slasher ethos) and the CW's “Supernatural” should simply include Blood and Gore in the cast list. Lately, however, those arterial sprays have left wider and more vivid patterns."
