Promissing.
It's not too bad, I've seen some complaints about the lack of detail to the animation, but it's not too much of a hinderance. It could be a little more fluid during action sequences however. Doesn't need to be more detailed, but the images just need to flow a bit better.
What's really got me is the sound though.
Using the actual language with the subtitles is a nice touch, but as soon as it fires into the modern rock, it just suddenly gets this "cheap" feeling. I also don't like how the movie and sounds seems to flow with an 'action/sound on, end action/quick fade." One minute there's no music, the next it's blaring. It just seems to break the mood in my opinion.
