It’s real simple: He’s not doing it “for” anything- charity, for example, awareness of hunger in Africa, for another, or even general homelessness/street bum type hunger- therefore it can really only be viewed as ego: “Hey everybody, look at me!”
Which, for an entertainer, is just fine. However, this particular stunt is remarkably pointless.
Houdini’s manacles-and-milk-cans stunts were at least interesting, there was, if nothing else, the element of “will he get out in time?”
Blaines’ stunt is, by contrast, exceedingly boring. He’s not doing anything, and his life, really, is not at risk. (I’m sure his handlers will pop him out of there the second they think he’s fallen ill or in danger of injury.)
So it boils down to the fact we’re watching an almost-static bit of new-ageish artwork that really isn’t all that interesting. For 44 days.
And in these modern times where a fifteen-second TV commercial is almost too long unless it involves a car explosion or partial nudity, and where even us enlightened web surfers’ eyes glaze over if the poster has written more than about a half a paragraph, forty-four days is entirely too long.
And so, the audience begins to participate. And how do you participate with a man stuck in a glass box? Hell, let’s throw something at him.
Is it right? Maybe not. Blaine, however, should have expected it- indeed, it’s good theater; look how we’re all talking about it, eh?
