Exhausting, this remake of a '70s anime film was produced at the same time as Sky Captain and the World of Tomorrow, using the same device of all-CGI backdrops combined with real actors. Well, mostly CGI backdrops, and mostly real actors. Too bad the one-note plot -- mutant race attacks the world and only a mythical superhero can save it -- is tired and dull, and can't even begin to carry its 140-minute length. It really wears you down.
