I think one of the really cool aspects of DCI this year is the wide diversity in show design where fans (like me) can appreciate the impact points and brass wall from Crown, the seemingly more cerebral Cadets investigation of Samuel Barber, featuring their kick-butt percussion and the fluid mix from BD. Since not one of the corps are truly clean yet (plenty of phasing, alignment and other flaws, even for the top 6), I find it fascinating to try to out-guess the judging based on my particular frame of reference. I would argue that a whole bunch of shows this year are highly involving and enjoyable, even if no scoring existed. Booing, I think, is in the 'grand American tradition,' but seems like more of a distraction compared with the creative product coming from these excellent ensembles.
