For Sci-fi geeks only please?

What's the deal with Tron Legacy? I thought Flynn was free to the real world. And why is it called Tron instead of Flynn. I mean, he was the main character right? Also I would like to point out Tron and Flynn coming off as the bad guys in this sequel. Assuming it was Tron who killed the guy at the end of the new trailer.
