But isn't that intended, in the first film efforts were made to make real people look computer generated and they weren't anywhere near as successful (even if by all reports I've read it's still the better film).

I actually thought that the young Jeff Bridges was some kind of makeup or stock footage effect when I first saw the film. I was amazed to find out after the movie was over that he was entirely computer generated. It looked 100% lifelike to me. It's the first time I was ever tricked by a computer. The uncanny valley is becoming less and less relevant IMO.
