That does remind me though -- Lindsay Crouse in House of Games is brutal and a fitting example here as well.
And Crouse is a GREAT example. A really awful performance which stands out even more because everyone around her is great using that same Mamet dialogue.
I love David Mamet. That man absolutely knows how to write.
Your point on Lindsay Crouse is very interesting. If you two have the time, try to find the Criterion version of the movie. I had the same reaction as you guys initially, but I have also seen her other works, and I knew she had more than that in her. Then I watched the extra features, and she explained that the detached style was what Mamet wanted from her, since she played a psychiatrist who had lost interest in her work and simply went with the motions. Observation is a large part of her training, and it actually helped me to understand her performance and also notice some of the subtleties she employed. I thought it also accentuated the climax, one of the very few times she showed emotions, and she absolutely nailed it.
To be fair, while I am still not sure if I liked her performance overall, I know that, at the very least, there is a purpose to her acting choice, and that it is not exactly her fault, as she simply followed Mamet's instructions.
