I think his material is great, but I can't watch him perform. I've got his DVDs, but can't finish them. He just seems angry. Then I read the things that he posts on the Cafe and confirm that he is angry. If you disagree with him, you're an idiot. His words. He seems to be very concerned with having a legacy and defending every bit of it. Those things aside, he's one of the most prolific magicians of the past century and he knows more about card magic than any living man should. He's a living legend in card magic and an amazing creator, but unfortunately wants everyone else to know and believe it.
Definitely agree about his posts on the Cafe. They make me almost angry sometimes, and yet people openly condone it! I like the way you worded that last sentence, very good stuff.
The Cafe condones alot of behavior that would be stopped at other places or at least looked down upon. As long as you're good friends with the owners, head mods or advertise on their site... you pretty much have free run of the place.
But enough about the Cafe.
The guy is a master at cards, nothing less than that. What X said about him, pretty much sums it all up.
