I have to admit I'm shocked at the response. My initial reaction was 'well that looks like shit'.
In order - I thought I was watching spaceballs when the token black guy popped up in the first scene. The rolling droid? Ok. That makes sense from a sand-world point of view. The young actor? I've had enough of young starwars. They fucked the entire series up with the first prequels, and I'm sick of teenie-adolescents angsty BS in movies just to draw folks in. This one could have been done without kids and I would have been very very happy. The lightsaber was also very meh - we had enough of the dark cowled evil BS with anakin in the 3rd prequel. The x-wing scene looked very nice, but the falcon scene was more CGI 'wave the camera around' BS and I really thought I was watching something from the clone wars CGI.
Darth Vader was Darth Vader. He was badass. He didn't need a cowel, he didn't need shadowy BS. He was just badass. You got that impression from his mannerisms. Like the fight on cloud city with luke. He WALKED through the entire fight. Why? NO need to run. He's going to win no matter what. You can run, flip, throw things at him, and he's just going to walk toward you and wade through it and win. We need a return to that type of bad guy. Darth Maul was actually a fairly good villain in the first prequel - the rest of the movie just sucked.
I didn't see anything there that I actually liked.
The next/last hobbit movie - now that trailer was good.
