And not to beat a dead horse, but she's a performer who performs every single night, every single matinee, 8 times a week. Well...you ARE beating a dead horse.
I find it absurd that people feel the need to put down a performance in explaining how good someone else's performance is.
Murphy earned some of the best reviews of her career in WONDERFUL TOWN, garnered basically every award she was eligible for except for the Tony (how Menzel ended up with the award is still hard to explain...and I am unabashedly beating a dead horse), and boasted a comedic performance that surprised everyone.
Shields proved to be the perfect replacement, someone who wasn't afraid to make the role her own, leave behind whatever Murphy had done with the role, and start from scratch making an equally effective Ruth.
