Wanted: New Database

I have a child.  I am always looking for new films to explore with him.  It's hard to find truly age appropriate films.  I have a pretty good handle on the classics, but we like to explore too (Check out our blog Bowl Of Noses).

How sweet it would be to have a database that sorts all of the films by the age of the protagonists?  Does it exist?  Will you build it for us?
