In that case Hanno Hagedorn is the guy you're after. His sculpture is beyond amazing.It's just the facial animation, although it's somewhat related to the characters' faces - those are very rough and unrealistic too. They're super detailed and roughened up on the males though, so most people don't care; and the females have other body parts to draw the audience's attention away.
But in the presentation itself, it's painfully obvious that they'd need a far better sculptor, someone with far more serious art background, to work on the faces. Not that I personally could do that much better, but we do have some painter guys here who can do really amazing stuff...
