It'll be interesting to see where technology will lead us in the Uncanny Valley.
Personally, I didn't have too much of a problem with the animations in Heavy Rain. I think the worst offender was Ethan Mars, his face was just too stiff to really show off emotion. That doesn't say anything about the game itself, which I personally thought was great, but there's still quite a ways to go before we see what the other side of the valley holds.
