So THAT'S why I thought Sims in TS3 looked weird! :P

"The uncanny valley is a hypothesis that when robots and other
facsimiles of humans look and act almost like actual humans, it causes
a response of revulsion among human observers. The "valley" in
question is a dip in a proposed graph of the positivity of human
reaction as a function of a robot's lifelikeness. It was introduced by
Japanese roboticist Masahiro Mori in 1970, and has been linked to
Ernst Jentsch's concept of "the uncanny" identified in a 1906 essay,
"On the Psychology of the Uncanny." Jentsch's conception is famously
elaborated upon by Sigmund Freud in a 1919 essay, simply entitled "The
Uncanny" ("Das Unheimliche"). A similar problem exists in realistic 3D
computer animation."
AHA! I knew there was a reason I found them so strange compared to
TS2! lol
