Solid meh. It kept me reading, but it really is Star Wars in Middle Earth. Not a bad selection for someone studying Joseph Campbell; this plus Star Wars are textbook examples of the Monomyth, but there's not a lot to set it apart from the rest of the pack. Elves are perfect, dwarves are grumpy, dragons are wicked cool, that sort of thing.
Paolini's prose is competent and gets the job done. Characters are archetypes, but they're fairly well defined. On the whole, it's not a bad book at all, it's just not particularly good, either. It definitely didn't grab me enough to want to read the rest of the series, but plenty of readers enjoy it, so that's cool.
