Along with The Incredibles, The Polar Express is opening this week. The general consensus seems to be that The Polar Express is creepy. This is explained by The Uncanny Valley, a theory about human response to near-humans beings (robots, cartoons, stuffed animals, whatever). The theory says that the more similar a being is to a human, the more positively people feel about it, until they get really close to human, and then it just gets creepy (uncanny in the original wording). In the case of The Polar Express, the eyes just seem really cold (Max says it’s because they can’t motion-capture the eyes).
