I liked the Biggs scene but it made only sense for those who new that there were more Biggs scenes from the beginning still waiting for their release. But I still have one question in mind about this scene: When GL wanted to give the SEs a modern look why didn't he use CGI to remove Biggs horrible 70s mustache? :-)
Back to serious: I liked the new look of Bespin. I liked the Banthas. Some more things but they are all minor.
WHAT I REALLY LIKED ABOUT THE SE: To see the films on the big screen.
