I honestly think that a bigger problem right now than characters that don't look realistic is characters that don't move or behave realistically. Stiff, robotic movements seem to be the norm. For a good example, look at the movie Final Fantasy: The Spirits Within. If the movement had been better, it could have worked, visually, but the stiltedness of the animation ruined the whole thing.
P.S. Thanks
