The script was extremely weak. Characters were never really developed. The main plot was not existent. It was a movie of perpetual subplots. The audio for the voices was really weird as if it was dubbed, which it wasn't if you watched the lips.
Most disturbing to me is the magic-steampunk concept. This seems completely lifted from Square Enix's Final Fantasy's magitech from the way it works to the mechanism to work it, but most of all the visual concept like the flying contraption.
Just not a very good movie.
