I havent read any spoilers out there... So I have no idea what you're talking about. I listed 12 random things that would suck if it happened in any star wars film... if you think a lot will happen, then the movie will be a total let down.
I however, think the movie will be good. I think JJ is a true SW fan who will give the fans what the want and Kasdan wrote Empire for God's sake. I've been disappointed before (Lucas PT), but this one seems to be different than the 1999 Phantom Menace hype / craze.
The only thing I know going into this movie is Kylo isnt a sith, but part of some group i've never heard of, I know the character names - have no idea what they are doing there, I know the tattooine looking planet is Jakku because of a micro machine set that came out that i saw, I know Snoke is andy serkis and i have no idea what he is, i know finn fights kylo in the forrest snow planet bc of the clip. . . Really, beyond that - I have no idea about anything of the story.
