When you get to see the end of David Tennant's first season as the Doctor, Episode 13, pay attention to his face. How big a Poser dial setting do you think you'll need to emulate that emotional expression? Something less than 0.2, I reckon. But it doesn't look emotionless. Think about it. There's a lot of inane, over-acted, expressions that were old-fashioned when Al Jolson said "you ain't heard nothing yet." It's all of them, and the emotion is as much in how somebody stands, or walks; they're acting with their whole body. How many of us do that with Poser? Oh, and it was a great episode.
