Interesting thread.
Disclaimer - I'm not much of a musicals person (now opera, on the other hand...) So I watched it partly because I felt I ought to find out what the fuss was about (and we had the Disney sub because of The Mandalorian - deeply shallow, our house!)
It didn't blow me away, but (this seems to be a minority opinion) I found the second half more interesting than the first. I thought the guy playing Jefferson absolutely stole every scene he was in (I liked Washington and Burr too). I thought "The Room where it happens" was a show-stopper.
I also loved Angelica - so well done, and some of the smaller cameos, such as Mrs Reynolds and the seduction scene.
I get what everyone's saying about Lin Manuel Miranda not having the vocal ability of the rest (and the worries that his insistence on starring made it into a vanity project). But actually the mismatch worked for me - because what I took away from it was his very hesitancy putting us "inside his head", self-doubts and all, compared to the very slick political performances of those around him. (And it's telling that his hesitancy is very much not how others see him - in the run up to the final duel, Burr's saying "he's got his glasses on, he's one of the best shots in the Revolutionary Army... I'm toast" - suggests that the "interior picture" of him as shy, dry financier is at odds with others seeing him as an able soldier.)
I was (as someone who is interested in the history of the period) blown away by the way Miranda could take what's actually a struggle over the ideas underlying the constitution (centralised power versus devolved, state-level power, centralised economics versus individual states' laissez-faire economics, dry, legal approaches to the constitution versus rhetoric and polemic) and turn it into a watchable musical. That's pretty close to genius, so I can see why everyone got so excited.
I think, on balance, I would like to see it live. There are definitely a lot of things that are just better in the theatre - "suspension of disbelief" works better there than on the small screen.
