Aw, I didn't realize that tonight was the season finale!
They did announce a few days ago that it was renewed for a sixth season, and given the Nielson ratings its receiving I don't see how they could cancel it at this point.
I personally didn't care much for it. They really are stretching the paradigm of the show. I understand why they would do so, but I think it's going to be either impossible or at the very least extremely difficult to believe to continue the partnership as we knew it.
