The thing I will always remember about Wilson is when he was acting as Lenart's "assistant" in the Green Magic videos. How he tried to look completely unimpressed the entire time. Maybe its just a Scottish thing.
Yeah it's not that he's cocky, and I actually really like some of his work and I will continue to support him, his persona just grates a little sometimes. He can be a bit patronising. It does seem to me a very British trait (I hadn't realised he was Scottish, although he has an obvious UK twang in his otherwise Americanised accent) but he comes off a bit of an arsehole sometimes. Not a dig at him though, I'm sure he's lovely and he's perfectly aware of the persona he puts out.
In the trick above the persona really works for me, because the kind of attitude he sometimes has you kind of want him to fail (as a spectator ) and he seems to mess up immediately in such a wonderful way. Calmly choosing a set of cards seemingly oblivious to the fact that the selection is one of them.
But then some people pull off those sucker tricks really well. Greg Wilson is one - his whole act is about entertaining his audience and making them smile, and he does this with bravado. He knows he's got chops, and he always has an out when he gets caught. Very few magicians can pull this off I think, as you have to be both likeable and challenge your spectators to catch you at the same time. Just do the latter and you're asking to be heckled.
