Cynthia Nixon did an amazing job as a woman with multple personalites. Until this show I had never seen her as anything but Miranda the angry redheaded lawyer on Sex and the city. It was fun too seeing Munch struggle with being the man in charge. Then, of course, there was the twist at the end that made it all even better.
I remember seeing Nixon many many years ago in a movie called Little Darlings I think. With Kristy McNicole I think. Anyway, she did a fantastic job in this particular episode. Had me going clean up til the end!! And you are right, SVU rocks!
