I didn't really like or dislike the new James vs. old James when I watched the footage, because I was too busy cringing at Mary/Maria and gagging.
I love Mary Elizabeth McGlynn's voice in most every situation, and I like her singing voice too, but it is really not appropriate in this case to me.
As I don't think I've ever heard her use the range of emotions required of these characters before. She tends to speak matter of factly, calmly, and at times quite boringly as Motoko Kusanagi. As Julia it was basically the same exact voice. On her spoken word parts of the SH3 soundtrack it was the same breathless monotone but it kinda fit as it was supposed to be pseudo religious creepy.
I am both intrigued and worried at how in the hell she will deal with such scenes as the elevator, the hospital recording, and generally anything in which she is supposed to convey anger/resentment/fear or any emotion at all really.
There is a reason she is best known as the voice of a cyborg.
