Saw it a week ago. Definitely the worst novel -> movie adaptation I've ever seen. I'll admit that it was the weakest book in the series, but that's no reason to defile it like they did.
Susan = Legolas. Aslan = treebeard. Do these people have any originality at all??
Peter was bone-headed in the book, yes, but did they really have to make him a complete moron? And the whole Susan and Prince Caspian thing, ugh. Part of the point of the books is that the kids were pre-sexual.
Really, it was terrible.
