Unlike American Idol and So You Think You Can Dance, America's Got Talent opens up auditions to a broad array of acts, from animal trainers to stilt walkers, welcoming solo acts and ensembles alike. But here's what's interesting. All four finalists, as you'll see in tonight's finale, are solo acts. And -- all four sing. Yup. Despite a wide variety of acts purposely selected by the judges for the top twenty -- the voting/dialing/push-buttoning audience has chosen a fairly homogeneous group of finalists -- four singing soloists. While it is probably true that American Idol has influenced how we vote, there is something much larger at play with America's Got Talent and all reality TV. Each is a hero's journey. Each involves thousands hoping to be called to adventure. And as we watch, and participate by voting, we begin to feel that we are on the journey as well. We've talked about this before, so now let's analyze/probe a bit further.
