SEASON PREMIERE: Normally, I wouldn’t highlight or recommend the return of this talent series as anything worth noting – but this is different, and this is exactly why NBC has made room for a new judge at its center. Piers Morgan is out, Howie Mandel and Sharon Osbourne remain, but this franchise will propel forward, or stall ignominiously, based on the reception viewers afford new judge Howard Stern, diving aggressively into mainstream pop culture. My guess? He’ll do just fine. Speaking his mind? Stealing the spotlight? As a broadcaster, these are the things he does best.
