Agreed.2nd trailer has dropped for those who want to see it... link below.
While I liked to the original Paul... I actually like this one better, just from the previews. He is more inline with what I pictured him looking like.
I am not totally sold about Zendaya as Chani, however I've seen her in only one movie (the Spider Man one) in which I felt that her acting was heavily influenced in a bad way by the direction. I am ready to be proven totally wrong. I still don't understand why they decided to change Liet Kynes as he would be Paul's father-in-law. The movie might clarify things, but when I read about the change I was seriously puzzled as Liet is one of those characters that is not central but at the same time is fundamental to move the plot and characters ahead. We shall see!
