That was one of my first thoughts, but after reading a bunch of the ratings, I don't think there are any ulterior motives.
I agree. Before jumping to conclusions, I actually READ the writeups. I saw a list of facts (and ones that seemed rather accurate for shows I know about) and in every show, a way to use the situation as a learning experience.
For example, 30 Rock. While it is not what the show is about, they suggest that you can talk to your kids and discuss how programs get on the air, how they are greenlit, what makes them worthy of air time.
Wow. What a concept, using a subject matter to actually engage with your kid and ask them what they think.
They are also one of the few rankings that I have seen that clearly delineates sex from violence, etc. You can focus on the items you think are important in your decisions making.
As for it giving you the ratings on the main INFO screen that some are complaing about (which tells me that they are either overly picky or have perfect lives is this is what they complain abuot). Big deal. They are using space that was dead to begin with. There was nothing there before.
