Yes. Of course, it will be "understandable" to children, as the basic plot doesn't really require much knowledge. It's very good for children (:) ) as a first step in exploring fantasy. Children (:) ) will watch the movie. They will want to read the book. And then, they'll get hooked! I think "Eragon" is a way to replenish our crazy fantasy community :) P.S. Everything is on topic! No one is arguing :) P.P.S. And the biggest pop culture is people.
