Combining elements of fantasy classics, from "The Hobbit" and Narnia and to "Star Wars", "Eragon" begins the Inheritance trilogy of adventures. In this first installment, a boy of mysterious parentage, from an isolated village, wandering alone in the age-old forest comes across a lost treasure: apparently a gigantic robin's-egg-blue stone, he brings it home. It hatches. Out pops a baby blue dragon. He cuddles it and feeds it and talks to it and builds it a little tree house home to sleep in. Pretty soon it isn't a baby. And it hunts for itself. And it - pardon, she - has some things to talk to him about. Soon there are strangers in town. They are looking for a lost treasure. They delight in extracting information. The reward and the punishment are about the same.
Luke - oops! Eragon - returns home to find it destroyed. He must leave on a quest, to find his own identity, and punish the killers. That takes him well beyond his childhood - home is gone. He must find a new life, and adulthood, on his own terms. Travelling with him is the old village storyteller Brom - to whom there is more than meets the ordinary eye. They get horses and move downriver toward the great plain beyond. And that is where the adventure really begins.
Elves, sorcerers, dwarves, men... evil, good, indifferent...
Pretty well told tho a bit predictable. As Reverend Billy says, a story without an unknown is an advertisement. (Which means, all the best stories are mysteries.) RevBilly points out that Eisner-era Disney movies, two-thirds-in where you expect the thrill of the unknown, instead hit you with fast-moving special effects. That is the challenge of the heroic adventure fantasy. How to make new - or unknown - what in form is familiar. The individuality and originality come in the telling of the tale.
That is where "Eragon" shines.
