I wasn't all that thrilled at first, but what got me excited to see it is the technical aspects. This is the first film I'm aware of that actually uses facial motion capture. Up to this point, bodily movements were motion captured, but faces were animated a la Pixar in post-production. This process was one that really annoyed me about movies that used CGI animation (which is more and more Hollywood films these days): you couldn't see the acting ability of the cast (but maybe that was a good thing...). With facial motion capture, we should be able to see the dramatic effect of the actors, even when CGI is applied. I'm not one to believe hype, but this technique actually does hold great promise, if it's done correctly.
