There are lots of issues to consider here, and KLG is only part of the equation.
First, Joe is right. Cheerleading would come off as fake, and I do not think anyone would suggest that. But there is a difference between being insincere and doing what it takes to work together to produce a succesful show. But as someone pointed out, this isn't a theater troupe, this is TV and the cult of the celebrity.
But I think a little armchair quarterbacking could be beneficial. First, I know Josh and consider him a friend. I also know that he is critical of his own work. So, I see nothing wrong with turning a critical eye to his appearance with the intent of learning from it. While those such as TheDean may confuse criticism with "not getting along" I hope others realize the difference.
The biggest problem I saw was Josh's lack of presence in the moment. It seemed as if he had already worked out what he was going to say and do, and was not willing to LISTEN to the hosts and RESPOND appropriately.
While all performers should have a plan and script, these encounters are about interaction. Josh didn't interact. Occasionally he acknowledged their comments, but he quickly tried to force things back on his own track. You could almost hear him thinking, "Ok, great, but what I was saying was..."
"Magic is like a story." Where did that go? It was forced and out of place. He was rushed. There was something there, but he did not take the time to expound on it. They didn't find it interesting or important, so we have a conversational mishmash with word vomit, not presentation.
When they were introducing him, he was not making ye contact and was not listening. He was playing with the balloon.
He did not acknowledge the post production pat down - a very real moment. "Real" is what people connect to. There was an opportunity here and it was missed.
Likewise, when the first card moment occurred, he should have let it breath. It was stunning. But (and I'm not saying I wouldn't have done the same thing in the moment) he seemed more interested in "getting to the punchline" than allowing this "real" moment to play out.
Now, I do not think this excuses KLG's gaff. But it became clear that there was a power struggle going on. The women had questions, Josh wanted to do tricks.
Would I have done better? Can't say. Hindsight is 20/20 and even more clear when one is looking at someone else's work. In this "magicians helping magicians" [censored] world we have created, people assume that criticism is condemnation. I am not here to condemn Josh, but to learn from him.
