I'm not overly concerned by this. After all, Disney did a better job with the Power Rangers franchise when they had it than Saban - the original owner - is doing now, and I'd like to think that they can handle one of my childhood favourites so well means that they can treat the Star Wars franchise with care. I'm content to wait and see what happens; I'm actually interested to see how they'll deal with the EU novels: are they going to establish a new canon, or try and make a film that doesn't interfere with it, I wonder?
Whatever they do, it can't possibly be as a bad as the prequel films.
