I saw it today--Dr. Sid (or Syyd, not sure)is the most realistic, IMO. I'll be curious what others think. One of the members of a digital photography forum I'm on was in the charge of the renderings and something else (not very far down in the credits--and before this was involved at Pixar with Toy Story, etc.). It was kind of neat 'sort of' knowing someone involved in it. Everyone is CGI, BTW Bia.
