This is a really good way to introduce the younger set to the Lord of the Rings Trilogy, who may find it difficult to read the books or to young to watch the movies.
I didn't realize this was geared for kids when I dowloaded it. As an adult, I was unable to finish listening to this narration because I found the voices annoying. If you listen to this with your children, be aware that many of the characters have high pitched voices, sounding like the Smurfs or munchkins (which of course, children love!). The narration of the start of Frodo and Co.'s journey seemed to go and on and they hadn't left the realms of Hobbit lands yet. I think they should have cut this down a bit so children don't start to get bored with the narration.
None-the-less, if you have a young one that you want to get into the science fiction realm, this is the perfect thing to listen too. When they get older, show them the movies and let them read the books for the complete Lord of the Rings experience.
