If you didn't know going in, this isn't either a film or a TV show. It's a recording of the Broadway play of the same name.
Admittedly, this play is for Americans who already have some idea of history. That probably excludes the younger generations, since the public school systems have gone south with years of Republican under-funding. (Seriously, some teachers make less than burger flippers.)
As a stage actor and a history buff, I loved this play and am so sorry I didn't get a chance to see it on Broadway. There are multiple reasons I gave this a nine, the major of which is that I'm rating it as a play, not a film.
First, I was blown away by the creativity. There is no spoken dialogue which is unusual for a musical. Second, it's done nearly all in hip-hop/rap, with one set-piece even in slam battle. The staging is great. Kudos for creative use of a turntable. I was blown away by the amazing, seemingly complicated, "rewind" scene.
Yes, it may or may not be historically accurate. (History, or "his-story" is written by the victors, isn't it?) It's good story telling. It's political. It's fun and it's touching.
