The show may not be going away any time soon, but the viewership is: compared to this point in the last season, ratings are down 35%. Nigel and company have been laughing off the competition since before the season began. That may be starting to die down a little. Voice is cutting into their fanbase and walking all over AI's theoretical credibility, their formula feels fresher than this one, and we're all just a little tired of the panel's ever-changing standards. (Broadway!) So naturally they're going to try and fix this -- by either going deeper into their own stereotypes than ever before in the hopes that purity will cleanse them, or by throwing a billion twists at what's left of the fanbase. And every singer will be praised endlessly. Because all of them could win every other show on the air. At the same time.
They reached the point where they thought they could stand on their reputation. And they forgot just what that was.
