I enjoy watching movies such as Air Bender, The Sorcerors Apprentice, The Craft, etc because many capture to a degree the astral side of magick--what is going on around us through energy that only some can see. To be able to see someone cast a circle that lights up with energy, create wind out of no where, it gives people learning the craft something to base their visualizations on. But it is, for me, just a source of entertainment. And most of the actual information is blown out of proportion or fabricated completely. But in a way, for a moment, to forget about the rigid laws of the physical lives we live and mentally step into the fantasy world of the movie, it's a nice vacation.
I don't like Harry Potter, not the books, not the movies. I don't see how the writer became so famous. There are far better books and movies out there.
