I do not know how much research the writer did into the occult but to my personal knowledge and research this is the best depiction of this type of actual "magic" that I have seen on film. It is a shame this film didn't receive enough credit for that. Hollywood is all about special effects, glamorizing, or demonizing what some refer to as "magic" when in reality it is actually quite different. This is an amazingly honest film that asks you to be honest about who you are and the lengths one will go to to realize what is truly important to you.
