Is it Monday already?? Well...
Well, a magician judge would be great to be honest. He/she/whatever would actually know what makes a performance great (which is very necessary, since Shin has raised the bar oh-so-high. In fact, that is what people SHOULD be sad about, that performing ambitious card on AGT won't get them anywhere now XD XD XD).
As long as of course the judge in question doesn't behave like a kid and try to belittle the one performing.
But then, imo, there should be a giant GRAND talent show which has an entire panel of judges from almost all performable and permitted art forms (98% at least) of today so that every performance is judged by both, its entertainment quotient AND the pure artisticness of the performance.
(Is there already a show like that? If not, and any TV operators or future-show-creators are reading this, feel free to use this idea but credit me
XD XD XD)
