I'm not 100% sure this movie will wow the general audience. From all the interviews that recently popped up, it sounds like Mangold is willing to take some risks with this movie; moving away from the 'obvious' comic book film, having a mostly Japanese cast, no huge names attached except Hugh's etc etc..
On the other hand, *because* of the risks, I think this has the potential to be amazing, especially for fans. This can be new, and unexpected, on a whole new level.
So what I expect is that it's either gonna amaze everyone, or it's just gonna amaze the fans (if the general audience actually *wants* a typical comic book movie..)
Either way, I have high hopes to be amazed.
