Yes, this is an important point. How many poeple, for example, who are aware of the Scopes Trial believe the narrative presented in Lawrence & Lee's "Inherit The Wind", rather than the actual history?
I've always been intrigued by the workings of collective epistemology.
Despite having lived the past 25 years in NYC, I very, very rarely attend Broadway shows. How ironic, then, that I did see Hamilton. Sitting front row center, tickets gifted by my sister-in-law, whose daughter was a huge fan & had seen it multiple times. I was in agony because the seats were close together, I couldn't move & my bad knee was acting up. Because our seats were so close to the stage, I couldn't get up & leave without being a distraction. LOL!
For all that, I quite enjoyed it.
Still, I'm very interested in what Toni Morrison & the "counter-play" have to say about it.
"Hamilton", however flawed historically it might be, has opened a conversation, along with Ron Chernow's biography, of course, about a figure that to most people adorned the ten-dollar bill, & not much more. The irony that without "Hamilton" the "Haunting of Lin-Manuel Miranda" wouldn't exist is pretty obvious.
Finally, I'd ask: does a musical have the same ability to shape popular history that a drama does? I honestly think not.
