It is extremely difficult for me to consider fantasy as "evil". I do understand the concerns. However, even C.S. Lewis SciFi triology could be considered quite occultish depending on the reader. Sword of Truth series by Terry Goodkind (is that is name, I forget.) is definitely very, very adult in content and quite occultish as well.
Yet, I enjoy these books. I have since I was a kid. The Narnia Chronicles, LOTR, they are no different really with witches, and other creatures, but at the heart of every book I mentioned is the struggle between good and evil.
I would not condemn a Christian for not reading these books or for not allowing their kids to read them, but I do not want to be condemned by enjoying them myself and for allowing my kids to. Admittedly, my kids are now almost 20 and almost 17.
