I'm not down with all this speculation and the brain bending questions left unanswered.
From what I've seen, there is real environment in the movie and to me THAT was the charm of the Original Trilogy and Phantom Menace (not including Jar-Jar of course). THAT is what makes the movies special for me. Tangible places and things that tie themselves to the real world, not that CGI crap.
I am happy to see that JJ Abhrams is honoring that. Like new Star Trek or not, he made them with the real world in mind and to me that made them enjoyable on their own.
I am excited for Christmas. I WILL be at the midnight premier with my daughter.
May the force be with us all.
