Caine brings up a good point: the musical Hamilton is deeply flawed, failing to address native Americans or slavery adequately. This is an important concern because one of the things Hamilton does exactly right is break the myth of the Founding Fathers as demigods spreading enlightenment and justice and freedom across the land. It is appropriate to take it to task for not shattering all the myths.
But here’s the thing: I can simultaneously appreciate the wonderful music and the strong story, and recognize the validity of criticism. It does not detract from art to say it does this one thing really well, but it does this other thing poorly; it does not mean that Lin-Manuel Miranda needs to go back and rewrite everything, nor does it mean the critics have to shut up and accept it as is.
It means the story isn’t finished. It’s never finished. There’s always room for more great art that tells another part of the story, and we’ll always have new art that portrays another part of the beauty and tragedy of the human experience.
