I think the problem is that they are a successful group using narration and singing, if they fell out of the top six i think this would be about the cadets anymore they would go after the next top group that uses these tools.
But isnt that the point of what the original poster is trying to make? Appealing to all audiences, not just dcp posters or die hard traditionalists? The show made some people angry but im pretty sure there are a lot of fans of that show.
