In grade school, Mrs. S., the vocal music teacher, showed our class a production of The Music Man--as a series of slides. As the class sat in silence, I thought, "I'm sure this is no one's fault, but wouldn't this be more effective if we saw it as a film or a video? A soundtrack playing under stills of a performance isn't nearly as captivating as seeing the actual performance."
I didn't hate what I saw, but I kept thinking, "This is basically a View-Master presentation with audio."
