The uncanny valley.

[Daftpunk]

Vagueness is creepy when it comes to the human form. This is what's know as the uncanny valley.

On a chart of humanness, there's a zone where something can be almost entirely human but off by just a little. No so wrong that its clearly fake or funny, or so good that its indistinguishable. It's just troubling. Between the mountains of safety and danger there is a valley of creepyness where the limits of knowledge and trust and security aren't very clear.
