I just don't get the antipathy towards ballads. They offer a change of pace, and give the corps the opportunity to display a completely different set of musical chops.
For the love of Hoppy, the main reason the 87 Cadets is one of my favorite Cadets show? The ballad, Make Out Garden Grow.
Can a poorly developed ballad be boring? Sure. So can a poorly developed opener or closer. Would you really want to give up, say, Pegasus, from BD' 82 show? Or Fire of Eternal Glory, from PR93?
