I still haven't forgiven C. S. Lewis for going on all those long walks with J. R. R. Tolkien and failing to strangle him, thus to save us from hundreds of pages dripping with the wizardly wisdom of Gandalf and from the kind of movie in which Orlando Bloom defiantly flexes his delicate jaw at thousands of computer-generated orcs. In fact it would have been ever better if C. S. Lewis and J. R. R. Tolkien could have strangled each other, so that we could also have been saved from the Chronicles of Narnia.
