If you pay close attention at the animation as it turns it seems to turn really abruptly. Try re-watching that one part a few times and you will see what I mean. It looks like the Dragon is switching really quickly between a turning animation and a swooping animation. But I thought that new technology they had eliminated this? Could this be that they are still working on it?
