First things first. DO NOT SHOW THIS MOVIE TO VERY YOUNG CHILDREN!! This is a very dark and often scary animation. I would recommend it as an 8 years and up movie, minimum!
And this is also this movies biggest problem. It just didn't pick a target market. It is neither cuddly enough for kids or smart enough for adults. Many reviewers have said how they were confused by the plot or that there didn't seem to be a reason for anything??? I found the opposite, this movie is very straight-forward, a little too so maybe. It is a simple tale of good versus evil in a post apocalyptic, alternative earth. (I fear the suits holding the money may have had something to do with the "dumbing down" of the story however and not the writers).
All this being said, it is beautiful to look at, with some fantastic set pieces and atmosphere and despite it's simple story, it is a sweet tale. The voice acting is solid (special mention goes to John C Riley for his ever-so-sweet portrayal of "5") and the action scenes are tense and well thought out. As I said earlier, the monsters in this really are quite creepy, even by grown-up standards, add to that the post-war setting and occasional images of (albeit CG) dead bodies/death and this really puts this movie out of the young kids film bracket.
"9" could have been so much more. In my opinion, it would have worked better as a grown-up animation with a slightly meatier script and the peril ramped up a little. As it is, it sits somewhat uncomfortably in limbo between kids and grown-ups, fully satisfying neither. Now, your thinking, "he gave this 7/10 and all he has done is complain!" well, it is a good movie and I did enjoy it a lot. It is haunting, thought provoking and beautifully animated and would have scored a 10/10 if it had just been written more towards older viewers.
A fantastic idea, lovingly animated. could have been a classic if it had just been a little braver in the writing phase.
