In a recent interview with Crave, J.J. Abrams actually recognized he had a problem with overusing lens flares in his films!
"I know I get a lot of grief for that. But I'll tell you, there are times when I'm working on a shot, I think, 'Oh this would be really cool… with a lens flare.' But I know it's too much, and I apologize. I'm so aware of it now. I was showing my wife an early cut of Star Trek Into Darkness and there was this one scene where she was literally like, 'I just can't see what's going on. I don't understand what that is.' I was like, 'Yeah, I went too nuts on this.'"
He even admitted that he had to approach Industrial Light and Sound to help remove some of the lens flare effects in the original cut of Star Trek Into Darkness. Does this mean we'll see a reformed Abrams by the time Star Wars: Episode VII rolls out? Maybe, but I would expect to see it in at least a couple of scenes in the film.
