Artemis Fowl as an anime? It just came to me this morning... We have magical girls/girls with guns, evil genius, monsters, etc.
EDIT: Jun Fukuyama as Artemis!
Ridley Scott doesn't usually make bad movies, just that the studios tend to screw up the editing and publicity. Kingdom of Heaven was really a damn fine movie, if more than a little historically skewed, but 20th Century Fox (I think) cut it into a love story, in the process excising almost an hour of it.
