Getting realism *almost* right is, as it turns out, horrifying. Imagine you Skype with your child but your face is slightly contorted. [shudder]. So they made the decision to not try and make it close-to-real, even though they can. They wanted to be sure the experience for all is enjoyable, so they dialed it all back.
Ahh, the dreaded "Uncanny Valley". Perfect example: go watch The Polar Express.
