LOS ANGELES: Computer animation has a problem: When it gets too realistic, it starts creeping people out. Most recently, moviegoers complained about the near-realistic depiction of humans in Disney’s 3D flick Mars Needs Moms.
A theory called the “uncanny valley” says we tend to feel attracted to inanimate objects with human traits, the way a teddy bear or a rag doll seems cute. Our affection grows as an object looks more human. But if it looks too human, we suddenly become repulsed.
