Completely agree with you. I see it as very poor reviewing etiquette. There's a big difference between the quality of the voice acting, and the script of the dialogue. While the script would be open for debate and personal taste, the quality of the acting is NOT. I've seen a lot of games over the course of history, and this voice acting is top shelf.
If you, at any point in time, get back in touch with whatever contacts you had to extort to get "lucky", do pass on compliments for a job well done.
On a sidenote, I fondly recall the legacy of Kain series in regards to sublime voice acting.
