what did you expect to see?
he does short, simple, hard hitting, in the hands, visual card magic (im oz pearlman, hi)
he doesnt need to do knucklebusting stuff to get the reactions that he get.
its not that you have a different opinion, its that youre an idiot.
Akirafist can squash your nuts into oblivion, buddy.
I have the theory that the effect is what people remember and tell their friends about, but the presentation is what makes them do this. However, Blaine's already on TV, getting crazy reactions from mostly black people and women (not to be racist in any way, but it's true.) He doesn't need to further sell his effect, the people at home are already captured by it, because this is the first time they've seen a guy go and perform those "mind-blowing" tricks on the street.
You know what I mean? David Blaine doesn't need to worry about having flamboyant presentation because he's already going to be talked about the next day.
If he had humorous patter, and a good personality, people wouldn't treat him differently than a guy on a World's Greatest Magic special. If he was like all the other pros, he wouldn't stand out.
