To play devil's advocate for a minute can I start out by commenting on how unbeliveably rude some magicians were throughout the whole of FISM not just through Belinda's act, several times through lectures, presentations, close-up, gala etc. you could audibly hear people talking away, and making comments etc. come on people learn some manners, it seems fellow magicians are the worst for this, would you like it if I came into your show and starting talking to my friends or laughing at what you were doing? Lots of times there had to be people loudly shushing the offenders, its just not on!
As to Belinda, I can say that I met her and told her how much I enjoyed her act, which was genuine, I enjoyed the setting and the premise, if I had one criticism it may be that the magic itself wasn't strong enough to hold up to the rest of it, but again that was personal preference.
Just thinking aloud maybe it was the fact the act wasn't in any kind of context, if you pay to see her evening show then you know what you are getting, to put this on first on a close-up gala may have been a mistake.
I certainly believe that as Magicians we need to be advancing not only our methods, but for me the most important part the presentations, and fine what Belinda did may not be to everyone's taste but I certainly appreciated the time she had taken in putting it together, and writing the script and making it into a show... we don't all have to go up to people deck in hand and utter 'watch this' and proceed to do the trick with no other presentation.
What Belinda did was what most of us should struggle to do with our magic, tell the audience more about who we are, what we do, why we do magic and how that effects us and the people around us, I for one applaud her for doing that.
