Well, I guess you should really watch Hamilton asap then if you liked In The Heights
Damn, that's impressive. You've never seen The Wizard of Oz or Grease ? The Sound of Music ? Trying to think what the most widely viewed non-animated musical is.Three of the best ever!
Highly recommend Singin in the Rain
The Hamilton movie is the stage show but filmed though, right? Not that that's bad, but not exactly the same
Dont worry about that and watch it ASAP
Just chiming in with an anti-recommendation: Don't bother with the 2012 Les Mis movie, it sucks so bad.
I really like The Greatest Showman.
