I like Common Sense Media. I didn't think I would like any media monitor for parents, but I think this one provides enough depth of information to put decisions into parents' hands. They rate and discuss several factors including not only sex and violence, but also consumerism, "is it any good," and "will kids want it." On the other hand, they also offer simple summaries. A parent who has specific criteria can generally just get a list of current products that meet those criteria.

The thing I like about CSM is if you hover over (or click on, I can't recall exactly) the ratings for each category they outline why which helps you make your own mind up how flexible you want to be with their recommendation.

Also gives good age ranges, not just the broad certificates.

I love Common Sense Media. My kids don't like to be scared, it negatively impacts their sleeping and frankly their general well being but I'm not really concerned about bad language or minor innuendo - CSM is the best way to get an idea if my kids are going to enjoy something.
