There are Christians who object to Lord of the Rings and also to Narnia books. Yet there are people who are lured into permanent loyalty to Christianity because they met him first as a fairytale lion. But there are also people lured into love of the occult by the portrayal of the supernatural in Lord of the Rings. or Harry Potter. It is a question that Christians have debated from the very earliest days!
