I've been told the music is really good. I've exclusively been told this by people who didn't study classical music or musical theater in high school or college.
I've listened to a bit, found it uninspiring.
Edit* I felt like I should give this a fair listen. Started the soundtrack a second ago.
Ok. I tried. Listened to it once all the way through, got about halfway through the second run then stopped. I stand by my original estimation. It's not bad by any means, like, the music all fits together well, and has some interesting moments but it doesn't engage me all that much. Maybe the stage show really makes it work well?
