Peace, I understand your perspective on the witchcraft issue, but I think this is because you are an unbeliver. Put yourself in the shoes of a believer, and ask yourself what you would do. If you are a believer, and you believe the Word of God, then does that alone not dictate that your desire would be to represent your beliefs with integrity by living them with your life? I think an argument can be made that if you are a believer, and if God says that witchcraft, and the like, is an abomination, then why glorify it, or familiarize yourself, or your children, with it at all in way of recreation, or imaginary play, respectively? God does not say it is harmless if in the form of a children's movie because it is entertaining, and watered down with good moral lessons. As far as Gibson's movie, I think an argument CAN be made for not having this 'image' of Christ, but I know that generally speaking most Christians do not consider this an image of worship unless they are worshipping the movie, or the actor. I think the key element here is the individual, honest, discernment of the beliver, or the family of believers, based on the Word of God, and the heart motive to sincerely please God.
A few here have listed the movies that they enjoy, and I do not prefer any of them, to be honest. I do not prefer fantasy, too much at all. That doesn't make me a legalist, or judgemental, as some may think. I do not judge others for their decision to allow these things, and I do not think that they are somehow more Christian, or less, because of it. I certainly do not believe that NOT exposing my children to these things is going to harm them. I do not feel I take it too far (that would imply that is has something to do with me trying to elevate myself), and I am not sure by whom's standards that would even be measured for any believer, and for any issue, other that God who is the judge of the hearts of men. I am who I am in the Lord by His doing, and it is a blessing to me, not a burden, even if I happen to fall into Nikki's "some people take this stuff a bit too far" category.
Eskarina, I have no views on Harry Potter, or on Narnia, other than I simply do not prefer them in general, and that the witchcraft is a red flag for me. I am not defending either of them, personally, but I was merely throwing out an argument (used by some believers) that I believe is justifiable, and is sensible to apply here. I would not use it, because I do not prefer either of them based on the witchcraft factor alone. I do enjoy some other of Lewis's works, however. I mentioned Pilgrim's Progress, and I believe that the truths that are depicted in this work, as with Holy War far outweigh my own lack of enthusiasim for fantasy, or allegory, so I do enjoy them completely, and allow my children to as well. The Lord bless you all.
