This movie reminded me, more than anything else, of "Final Fantasy: the Spirits Within." I think that critics of movies like these sometimes criticize them for being A: animated, and B: science fiction. That's sort of like criticizing "Terminator" or "Lord of the Rings" because, as one reviewer wrote: "that could never happen." Well, yeah. I mean, isn't that the point, to create something that can only exist in the imagination? I have a hard time seeing the relevance of comparing "Kaena" even to other animated features like "Toy Story" or "Ice Age." SciFi is a genre unto itself and needs to be judged on its own terms. "Kaena" is a fully-realized fantasy. It has a comprehensive story, background and setting. The voice-over narration (English) is particularly good, especially Kirsten Dunst in the title role. The only real criticism I have is that the quality of the animation is uneven, ranging between mid-90's video game at one extreme and almost breathtaking at the other. The choice of a very muted color palate for most of the scenes doesn't quite make up in atmosphere for what it loses in vibrancy and realism. Overall, I give "Kaena" an 8 based on the strength of its story and characters.
