The best this movie can probably do is to just destroy the franchise without ruining its legacy too much.
How so? Explain.
1. The movie hasn't even begun principal photography yet. They're still casting and in the middle of the pre-production process. We don't even have full, official confirmation of anybody's involvement in the film other than the few names at the top of the production and direction heap.
2. Original Trilogy stalwarts are going to be involved. Lawrence Kasdan played integral roles in making Empire
the popular, beloved modern classics that they are. J.J.'s many things, but a complete egomaniac and dictator who doesn't listen to others on his staff and is deliberately trying to sink entire franchises isn't one of them.
3. Disney, Lucas and Kathleen Kennedy aren't going to put this cherished franchise in the hands of a complete idiot who can barely direct a beer or tampon commercial. J.J. is a tried and tested factor who - whether you liked the last two movies or not - revived the Star Trek film franchise after the tanking and failure of Nemesis,
a film even many die-hard, committed Trekkers didn't want to see. Abrams isn't Lucas. He's not Kershner. He's not Marquand. But he's not a chump or a putz who is going to torpedo one of the greatest franchises in the history of popular entertainment.
Again: how is he going to destroy Star Wars
