We went to see the Eragon movie last night and I reckon that it is a good argument for waiting till you've seen the movie before you read the book. I was totally disillusioned by it.
I can understand that Christopher Paolini's book is not translatable into a 2 hour long screen format. However, the makers of the film managed to take all the fat and most of the nutrition out of his wonderful epic plot, reconstituted it and squeezed it through a mincer. I enjoyed a lot of things about the film, but as far as the plot was concerned, yeugh!
