This is just a newer edition of the Gong show.
Watching these shows is a tremendous waste of time.
Or Starsearch. Or Ted Mack's Original Amateur Hour.
These shows used to be on in the afternoon, or in the hour before prime time viewing began. Now networks are built around them. I honestly don't understand sudden appeal of these talent shows.
I guess folks like to see the fake contestants that are only there for our amusement and are made fun of by the judges or something. It's only a couple of steps up from Jerry Springer Show, IMO.
