The Uncanny Valley

In Moana and Frozen, they look a little bit more like people. And then out of nowhere, this line that's just been going up very pleasantly at a nice little slope just drops downward. And it doesn't drop just downward. It goes actually below the x axis into negative territory. And now this is the uncanny valley. That's why it has that name because it's a valley. This is where those things like really, really lifelike androids live or corpses live or zombies live.
