Your right - dangerous to speak for the masses. I think it's reasonable to say that some significant percentage of fans believe the changes in shows (synth, dancing etc..) are not preferred over good old fashioned percussion and brass. (And btw - I do believe that the general talent and execution of BD in more than noteworthy........ this is more a discussion about design and subjectivity)
I find that the rationale I hear from BD (and I'll throw in BK this year just for good measure ) fans seems like a paradox. First, most BD and BK fans are quick to point out how the judges appear to like what they are doing... and I'll admit, that does seem to be the case. One was crowned champion, and the other received significant "attaboys" for multiple categories that are arguably very design driven.
But the minute one begins to question whether the judges have it "right"; they start down the entire - "it's art"; "it's subjective and evolving"; "You can't limit creativity with ...." "DaDa ..." you get the idea.
Well - isnt this entire discussion just a bit circular? Doesnt that line of thought turn the tables, and make the dinosaurs who perform old school marching drills the creative non-conformists? And suddenly it is the artists delivering the evolution of creative license to the masses that are using the stifling standard of a scorecard to justify what they are doing..........
Hmmmm, kinda makes my head hurt.
