This is not a film that has aged well at all. The movie was done entirely in computer animation. CGI is fine and can add a lot to films that need it, but it requires that the film take on a style of its own. Here the process seeks to imitate real life, and for what reason I'm not entirely sure. In the right light, it almost works and is almost believeable, but these scenes are few and far between, instead you get scenes that look like they came out of Playstation 2 cutscene.
I'm not usually hard on cinematography or animation style but this movie looks downright bad to a point where it has a debilitating effect on the rest of the movie. The story is nothing really worth writing home about, it's not great but it's not terrible either. There's a nice climatic battle, that somewhat redeems the terrible animation but it's too little too late.
