I went the day after it was released in the US and by the time I was exiting the theater, the songs were stuck in my head! The only problem I had was that the songs on the soundtrack aren't the full version. It's better than nothing though! Personally, I don't think Russel Crowe and Amanda Seyfried were as bad I hear people keep saying.
I'd like to read the actual book someday and maybe watch the Broadway revival if it comes back in 2014. Has anyone read the book or seen a live production/movie?
