I could not be more annoyed with this "Rappin' Granny" crap. If the only thing that makes an act interesting is the age of the person doing it, then it is NOT TALENT.
Ditto for the 12-year-old divas.
If a 25-year-old did the exact same act with the exact same talent level, no one would care.
Now talk about the magician who appeared behind the judges, Realis, or the Contortionst Archer. That is an actual talent. I am usually more enteratained by the weird acts that they show on the results show. The HOUR LONG results show, but that is a different matter.
