I'm going to see it, because I've followed the series most of my life, and I suppose also because of the action.
Does that mean I do not dislike character development? No. I appreciate it tons.
However, it doesn't mean that I dislike the mindless action. I'm not going to feel anything during the film, and if it's a waste of two hours, that sucks, but I still think that it will be at least mildly interesting.
