it won't let me comment... Binary_Illusion .. you mean the necklace he wears? haha its an "A" with a backwards "C" -- Criss Angel... yeah. he's not a devil worshiper.. he worships God. watch his movements and actions before every demonstration.
I don't believe in magic, it's all an illusion somehow. Wither it's a mirror or a fast hand. Or decieving the audiance by paying actors to watch his "miracles". I also think the symbolism he uses, the pentagram for instance, is to add to his allure. The pentagram is not a sign of the devil, or anything demonic, but Hollywood as portrayed it as such. He also wear black clothing and mascara, leading you to believe he is dark and mysterious, possibly having mystic powers. But it's a sham, he's on television, you are watching, he's making money.
But to answer your question, he is just another entertainer. And he is entertaining from time to time, its fun to try to figure out his tricks, just like any "magician".
