The Uncanny Valley is a theory in robotics that states that the more a robot looks human in its looks and behavior, the more empathetic a human will feel up to the point where it’s “almost human” and that empathy quickly turns to revulsion. Once it passes the uncanny valley and is fully humanlike, the revulsion turns back to empathy.

As another example, zombies are creepy to us because they are almost human. They look human, but they don’t quite behave like humans.

Now, watch this video. It’s not a human-like creature, but for some reason I had the same revulsion/creepy feeling while watching.. especially at a certain point in the video. See if you can pick it out…
