Beautifully Drawn - Poorly Scripted
Unfortunately this does not have a strong story to it. But it is beautifully rendered. Anna Paquin, Patrick Stewart and Alfred Molina provide the voices. Though Anna Paquin's attempt at a regional accent is pretty dire (to English ears).
I would only recommend this film if you love Japanese animation. While the story is somewhat passable, it doesn't really make sense and hold together very well. A Grandfather, Father and Son at odds with each other over the possibilities steam power at the advent of it's discovery - you can never quite understand just why Patrick Stewart is so vehemently opposed to his son, nor why his son seems to have become a virtual zombie (modelled on Frankenstein's monster), nor how the son manages to determine good from bad, with this terribly muddled storyline. This film tries to create an air of tension and suspense which is supposed to make you intrigued as to the 'rights' and 'wrongs', but unfortunately manages to muddle it so much that you don't quite understand where the story is going.
