In my opinion, this show should have stayed on Sunday nights and should not be cancelled at all. I can't believe that NBC is giving up on this many fans and viewers so that they can put shows on like The Bionic Woman, Baby Swap, and Singing Bee.
Maybe viewers should be aloud to vote on what they want to watch instead of letting the networks decide.
