I still don't think it's that hot. To me, it looked like they tried to map a CG texture over a live actor, kind of like they did with "The Mummy" to create the half-desiccated, half-regenerated scenes. ...there's still somethign a little stiff or plastic to the movements. If I didn't know this was CG, I would have thought she had way too much plastic surgery or Botox, and her face was partially paralyzed.
..as far as the best CG to date, it is a toss up. So many movies go for a stylized look, there are few that try for true photorealism. Shrek and the PIXAR movies are all stylized and cartoony. Final Fantast VII: Advent Children has a dreamy, androgynous, anime look. My vote would have to to go the new Star Wars trilogy for most photo-realistic, even though there weren't really any CG humans
