I'd be the first to admit that you are basically correct, I dislike a vast majority of broadway musicals. There are some musical movies I like and things like Book of Mormon which I'm not sure if it's considered broadway. I find Le Misrables to be okay.
But I would still have to say, amongst all the broadway that I don't like, Hamilton sticks out to me as especially weird, like one of those 90s educational videos where people would rap when they clearly just shouldn't be.
Anyway, to each their own. More power to you if you like it. Something about it really bugs me though.
