Commonsensemedia is designed to help parents review media choices both before and while their kids are involved in them. It allows kids, parents, and educators to review material.
Their mission statement is helpful:
"We exist because our nation's children spend more time with media and digital activities than they do with their families or in school, which profoundly impacts their social, emotional, and physical development . As a non-partisan, not-for-profit organization, we provide trustworthy information and tools, as well as an independent forum, so that families can have a choice and a voice about the media they consume."
