What does length of a show's run on Broadway have to do with what is a "better" musical?
I do not think Band's Visit is *better* than Hamilton, but I loved both. Not equally - I loved Hamilton more. But I don't think it's because of how long it will run, or the running time either.
Assassins is shorter than Hamilton and maybe the same length as Band's Visit, and I think it's probably better than both.
