To some degree, it might be because of difficulty to connect with the theme of a show. It's getting harder and harder on some of these to understand the theme. Blue Knights are a prime example. If you don't understand the ancient Egyptian mythology behind it, you won't get the show. Mandarins to some degree, Genesis, Phantom, and Colts as well. On the other end of the spectrum, Boston, Music City, Crown, Academy, and Blue Stars are all easily engaging. I like every show out of World Class this year, but I've studied them all and get them in a way a one time spectator who hasn't studied them won't be able to.
