I am currently reading Planet Narnia by Michael Ward. I am only halfway through, so this is not a full review, only some thoughts. I just want to catch you before you appropriate all your Christmas money; this may be a book you want under your tree with your name affixed to it.
The primary reason to read this book is that Lewis was a genius and the Narnia movies are, to put it bluntly, not. If you are watching the movies but not reading the Narniad to your children, then your children are learning lies about Lewis. Although it may be formally true that the films were “based on books written by C. S. Lewis,” it can only be true in the meanest sense. The movies are “action/adventures” for children; the books are the subtlest of fairy tales. The movies are the epitome of unliterary, while the Narniad nears the apex of literary. The Chronicles of Narnia are sublime, and Michael Ward proves it.
