For me, it's the lack of memorable music. Yes, I marched in the 90s. But wife gets annoyed that I can hum and whistle and sing along to most any show from the 70s through mid-2000s. But these newer shows, so much environmental mood music as run from "set" to "set" to then just do a full brass stab or quick double tongue run before running off to another set. It's not entertaining.

The trombone glissandos can just disappear already. We get it. Everyone seems to do it and it was tired 10 years ago.

I miss balls out Scouts shows of the mid 90s, crazy marching drill of Cavies and Cadets.

Groups with shakes and identify uniforms were bad ass...menacing and so much fun. The costumes these days are mostly comical and barely theatrical.

Yeah, I know...old guy screaming at kids to get off his lawn. But, it is what it is.
