Who would've thought that "The Voice" could serve as a shot in the arm to competitive reality shows? While this is in many ways an attempt by NBC to tap into the base already established by "American Idol," the show's 11-minute preview (which you can see here) does a solid job at showing us why exactly the show is different.
The format bears some similarities to "X Factor," as Christina Aguilera, Cee Lo Green, Blake Shelton, and Adam Levine all serve as guides to help 32 people (or eight each) attempt to realize their dreams of superstardom through a "blind audition." The kicker is that they are each competing against each other. The clip shows us a young man who three of the four coaches want to help mentor, but he can only choose one of them to work with.
The main reason this show works so far is simply that the coaches have personalities -- Aguilera and Shelton are in particular hilarious, and Levine and Cee Lo ge their share of one-liners in there as well. The only real question is how they will actually critique contestants later in the show (in some ways, it would almost be better if they found a way to minimize the trumpet-blowing for each contestant that has been happening on "Idol" this season).
