So I'll disclaimer this right off the bat as my subjective opinion and if you disagree, fantastic, enjoy your freedom.
I do not, nor have I ever liked, JJ Abrams, and the reason is primarily because he's not Michael Bay terrible. JJ Abrams is a limp grip handshake of a director. He's a watered down beer of a director. There's no substance there, not really. He's a master at creating something that checks off every box on the list of what has to be in one of this or that type of film in order to be "successful" coupled with a deft marketing hand. Star Trek, I found, was incredibly mediocre. It had the characters, it had the ship, it looked (relatively) nice, but it didn't have any spark. No life to it. It was bland and tasteless and quickly forgotten outside of the most surface level of viewing. (Thus all the lens flare jokes. No one could remember anything more important.) Likewise, Super 8 was a bland photocopy of Stephen Spielberg's style. He can imitate, he can create something unique, but it all falls flat in the end because there's nothing there to really take home and chew on.
For all their many (MANY) flaws, the Star Wars prequels did give us a few things to think about. Honestly, as much as you might hate Anakin in the movies, the idea that the bloated, bureaucratic society that supported the republic was the greatest component to its own downfall was well-reflected by the fact that the films themselves were taken down by almost the same thing. (Not a fat joke at Lucas' expense, but rather a comment on the films being a product of their own bloated, self-important origin.) And those films did check off everything on the list. We had jedi battles (some very good and some truly awful), red lightsabers, obtuse dialogue, several planets, and an incredibly obvious, contrived, and linear storyline. That's Star Wars, guys. It was the love and the dedication and the life of it all that made the old films work, not quality writing and directing.
Abrams is many things, but the three people most likely to murder a franchise are its director, its writer(s), and its casting director. Abrams is, imho, a red mark on that list. With Disney's power behind it, I'm hoping the first is saved by the other two, but I'll not hold by breath this time around. Then again, it doesn't matter, because the next Star Wars films are already guaranteed to make more money than (insert wildly inappropriate simile) on name recognition alone, so I'll just sit back and enjoy the fact that the greatest living actor on Earth will be in it and, good or bad, I'll enjoy that. It can't be worse than Indiana Jones 4... can it?
