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
