When I first saw the trailer for this movie a couple of months ago, I didn't realize for a few seconds that I was watching a completely computer generated footage. But after a while it became evident that it was. But that didn't bother me. After all if all the CG movies looked like "real" movies what would be the point of making CGI movies? (Other than saving money on hiring big name actors maybe?) But what did bother me was how eerily creepy the characters looked in the movie. The same creepiness (so called "Uncanny Valley") that we've experienced in Polar Express. I think the technology got a whole lot advanced since PE but it seems it still has a room to grow. I think the whole weirdness stems mostly from the computer generated characters' rigid facial expressions and those staring eyes.
