I liked this trailer because it gave us a bit more... for those who haven't read the books and don't necessarily know what's going to happen, this trailer sheds a bit more light on where the story is going. I think it also gives us a better look at Austin Butler's character - we only got barely a glimpse in the last one, but this trailer we start to understand his character a bit more - and that he is going to be the adversary to Paul.
