I tell my kids that appreciation is recognition of the worth of something, but that like is a feeling of wanting to experience more of the same or of similar. (I explain that I appreciate country music, but that I do not like it.)
I appreciate the amazing talents of the current corps' kids, and I appreciate the abilities of the designers...but I don't like much of what I see or hear. Particularly hear...I have had no desire to listen to the entire top 12 for a LONG time...a few corps shows stand out (2006-2008 PR, 2008 CC...uhh...that's really about it for recent years), but I just don't like many of the shows these days as musical performances, so I don't seek out any more.
I am bothered by the WGI-ification of the activity, but I'm still of the vein that the activity originated as a musical experience that has added visual components...when he visual component has become the driving force, well then, I'm just too interested in shows that stay in my head as musical experiences...ones I like.
The best example I can think of from my personal experiences came in 2003...the biggest audience reaction of the night at Finals came for PR...because they forced the audience to stand out of sheer gut reaction...no appreciation there until after you realized that were you standing and had no recollection of doing so...just like when I saw Vanguard in 1986 and knew I had to march drum corps so that I could do that to people...
Anyway, I have been spending my money on stuff that I like, and I wish the kids in the activity all the best.
