Maybe I’m overstating the impact of “Hamilton”, but Lin-Manuel Miranda may have done something revolutionary. In the end you have to give the people what they want, and “Hamilton” does precisely that; it blends our insatiable appetite for history with music that is relatable to the under-40 crowd which is not “all-in” on the retreads. I can envision LMM “copycats” originating similar content and making this the preferred genre of American musical theatre for some time.
