I mean, think about. His aunt and uncle were totally protective of him, never allowing him to make his own choices. They seem to know about his father, so they're scared. Comes along Ben, who basicly says 'you should stop listening to what those people are telling you, and do exactly as I tell you'. No free choice at all. Next up, Ben is killed and he's roaming around the galaxy as a hunted man basicly. Untill a ghost tells him to go somewhere and be told again what to do and trust his faith into some unseen Force. He's basicly told that recueing his loved ones is not allowed. Then he finds out his father isn't dead, but an evil tyrant. AND it turnes a man he wanted to trust never even told him he had a sister. With only basic training in the Force, he's now also given the order to rebuild the Jedi Order (pass on what you have learned). This totally backfires, and his own kin slaughters the whole bunch of his students. Really, messed up and scared Luke from the trailer makes total sense. Now, yes. That was a silly post, I understand. But, I know some fans are disappointed at the portayel of Luke in the new trailer. But really, look at what he's been going through all his life. There was no true stable core in his world. Even the upbringing by his aunt and uncle had a root in fear. A dapper hero would have been awesome, but this idea of a man on the brinck of loosing his last shred of sanity..... It makes more sense I think.
