Absolutely! And the reason? Well, it's not just the CG being good, it's that those CG characters are imbued with very strong emotional depth. They are victimised, subjected to violence, have relationships, friendships and they are made to suffer an incredible amount of fear. They are emotionally complex.
The result? We care about them. I can't say any other CG characters have ever elicited the same response from me. Not Gollum or King Kong, because they're not as accessible. But the "prawns", the father (Christopher) and his son, not them I cared about. Wonderful stuff.
Fantastic film.
