BGT ruthlessly pushes singing and musical acts over everything else. It's judged, edited, packaged and press-released so that music, especially singers, dominate.
Why should this be? Could it have anything to do with how much money Simon Cowell can make off of music downloads and CDs? It's hard to cash in on a talented cyclist or a trapeze or dog act or whatever.
I would ban children completely (from BGT, not the planet, obviously), singers and keyboard players. Both the keyboard players in the final are worse than the average people you hear in any town music festival up and down the country. One has no personality at all and the other has WAAAY too much.
