I agree with the last couple of posters. I don't think it's overrated because people aren't calling it the best musical ever, just a very enjoyable, fun time that is flawed, but endearing.
carousel94- You are not alone in your love for the score. It may not always greatly advance plot and character, but it is so insanely and damnably catchy that it truly could drive a man mad trying to drive the tunes from one's brain.
Good luck if you start humming A Man Could Go Quite Mad, Two Kinsmen, Perfect Strangers, Don't Quit While You're Ahead, Never the Luck, No Good Can Come From Bad, Ceylon or Wages of Sin in the morning, because you won't be able to stop all day!
Part of the thrill for me personally was finally getting to see a production live onstage. After loving a cast recording it was fun to see how it all fit with the action, and since this production is so expertly sung it was hard to find complaints. It fulfilled what I was looking for in Drood- but we all come to shows with different stories and desires.
Marie: Don't be in such a hurry about that pretty little chippy in Frisco.
Tony: Eh, she's a no chip!
