"I can tell there's going to be a LOT of contorversy about whethere Gerald is good or bad. "
Yes, over on the film's offical site message board the opinions are quite varied, with several people saying that he improves upon multiple listenings.
Personally, I thought he sounded fairly excellent, especially considering the fact that the man did not start serious vocal training until just in the last couple of years (I read somewhere he started training during filming of the second Lara Croft film). He's not a perfect singer -- I hear him breathe in spots where more experienced singers would not breathe -- but I didn't hear him go off key -- although there is one spot in the title song where he slides down from "me" to "they hear." His passion and pain at Christine's betrayal after "All I ask of You," is clearly heard in his voice, and his "You will curse..." gave me chills. In MOTN he whispers, cajoles, and is seductive... sure convinced me to want to listen to his music of the night

. I liked his Point of No Return, and the stuff following that was great.
I thought Emmy sounded wonderful. I didn't hear any problems with her high notes -- in fact, when she hit the top note at the end of "Think of Me" I got a shiver up my spine. Her voice and Gerry's seem to blend well together. I didn't detect any shakiness on her high notes at all, and was impress with how good she sounded on the low notes. Wonder what her range is?
Patrick, I didn't really focus on too much -- too focused on Gerry Butler, I guess

. But he did seem a bit breathy in spots, although I have to say it seemed to work when we first hear him in "Think of Me." The way I imagine it, he's seeing Christine for the first time in a very long time, and the sight and sound of her have left him breathless. I liked the spoken dialogue during Masquerade by Raoul and Christine.
I have to listen to it again, but overall, I'm very exited about what I've heard and cannot wait for the film.
