@scout59 - While it was hardly the first nor will it be the last great musical ever written, it is groundbreaking in so very many ways. (And there are no shortage of mediocre or less-than-mediocre musicals out there, so there’s that, too)
I saw Hamilton in Boston today. I know the soundtrack backwards and forwards but seeing the full production with choreography made it three dimensional. The cast was outstanding, the ensemble was perfect. It will stay with me for a long time. Now I have to figure out a way to see it again (and take my daughter.)
