I think one thing that I look for in any new Star Wars movie is its willingness to take us to new places.  I think that desire comes from the juxtaposition in A New Hope of the vastness of space and the emptiness of Tatooine.  So while there are a number of nice moments in this final Star Wars trailer, I am most enthralled by the possibility of new places with different horizons.  There are a few great ones in this trailer.
