That's your opinion. I disagree, but i can respect what your saying. I think Chicago is a great representation on scandal in the Jazz era, and even though Kander and Ebb scores aren't my favorite, i still am aware of how good their scores are. Chicago just never appealed to me.
Some can say Rent is "sophisticated, brilliant theater". I, personally love Rent, but wouldn't say that. Does that mean i'm wrong? No. Does it mean the person that says Rent is sophisticated and brilliant is wrong? Also no.
So while you say Chicago is sophisticated and brilliant, i say it's not. Either way we're both right
