Please no. God no. The Artemis Fowl books are good but that movie is an abomination that only shares a name with the books. If they were to bring it into Kingdom Hearts it would be a world inspired by the movie which was nothing but a failed cash grab. The books were interesting with such great world-building. You could really get behind what they set up. It wasn't One Piece levels of world-building but it was so good for a non-Japanese property. Please, don't remind us of how terrible that movie turned out to be.
