bon8rich, I used to think Caroline wasn't subtle and spoon-fed it's audience (like when Caroline shouts "I can't hardly read") during "Lot's Wife". Don't get me wrong, I did feel it clearly had a great score with rich music (with great melodies), but I didn't get how brilliant it was and how much of it flew over my head until I actually listened to it about a year or two later (and I grew up some).
I think it's an incredibly American story about struggles most of the working-class can relate to. I think stories like Caroline need to be told more often because most people are like Caroline who have struggles with their dreams and life not being what they thought it would be. Bitterness, resentment, and anger but also acceptance and getting through life and trying to kill the part of you that makes you hateful. I felt it was incredibly moving, and I was glad to see a show with so much thought given to ordinary people (not just show people or middle to upper-class WASPs) and showed them battling their struggle in a realistic way.
"I've got to get me out of here
This place is full of dirty old men
And the navigators and their mappy maps
And moldy heads and pissing on sugar cubes
While you stare at your books."
