I just recently saw the show, this past weekend, and I found it very good. Sandra has a very slow wide vibrato, it is not horrible, but it just takes time to get used to. She was flat at the end of Think of Me when I saw it, but that was the only major issue I had with her. Her acting was very good, and her Wishing made all the people around me start to cry. I don't think she is worst christine, but she is not the best I have seen. I liked her acting especially towards the end of Act II.
