Common Sense Media

I was looking for a movie review to help with picking a good movie to go to and I ran across this site that might be helpful for families with kids. It is called Common Sense. They appear to be free, have a newsletter and have reviews of movies, TV, music, books and web sites. This is their mission:
Our Mission

Common Sense Media is dedicated to improving the media and entertainment lives of kids and families.
We exist because media and entertainment profoundly impact the social, emotional, and physical development of our nation's children. 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.

Our Beliefs
Media is fun and our kids love it. We also know that kids now spend so much time absorbing its messages and images that it has become "the other parent" in their lives. We started this organization because we know families need trustworthy information to help manage their kids' media lives. We're posting our beliefs here so that all our users can know the underlying principles that guide our philosophy and mission.
