@edgarblythe,
I always found her to be a lot of fun.
I think shows like American Idol and America's Got Talent need to be regarded as mainly entertainment, and not necessarily vehicles for finding the best talent available. As I alluded to earlier, the voting process certainly makes a mess of that. Sometimes it's more of a popularity contest than a talent one.
This year, America's Got Talent has not been too entertaining, with a lot of bogging down in contestant backgrounds and way too much drama with drumrolls.
Ellen will add a nice lighter touch to AI.
