There has been quite a bit of debate on whether or not it is OK to read Harry Potter. I have never been remotely interested in the books or the movies so I have little direct knowledge about them. I did read awhile back when the first books came out that the exorcist of Rome, Fr. Gabriel Amorth found it to be demonic. In 2002 he said, "Behind Harry Potter hides the signature of the king of the darkness, the devil." That seemed to be pretty strong language, yet many laughed him off. (More here and here) Another priest, Fr Donald Calloway recently commented on it, and the video below lets you in on his opinion.
