Dan McCoy’s review published on Letterboxd:
It's super charming that David Byrne happened upon color guard, said "YES. I like THIS. People need to see THIS," and proceeded to mount a large-scale arena show highlighting 10 top color guard teams performing new routines to live music by some of his favorite musicians. And when the color guard teams are doing their routines, it's fantastic, and you get why Byrne was enthused.
On the other hand, I didn't connect with the non-performance parts of the movie, whether it be some flashes of verité backstage footage or snippets of interviews. I just didn't care.
But, hey. Those performances, tho.
