It's here:
I saw JJ quoted very recently on fan complaints of the kind you are referring to and what he said was something like "stay home and be angry" so just don’t see the movie, if that is what your life is about and that is the way you want to envision your relationship to Star Trek and the world, fine. This is a movie. It is a movie! You want to go see it — chances are you are going to enjoy yourself if you open your mind to it. If you go to see it to find fault and to point out the things you think are inconsistencies, chances are you won’t have a good time and you would have wasted your time and money so why bother? But if you go to it with an open mind, I think chances are very very good you will see very well made and interesting movie.

there are some directors who can do that very very big canvas, like a Michael Bay for example, stuff that is big and bombastic. There are some directors who can do intimate, inter-character relationship moments. And not a lot of directors can do both, and I think JJ can. He has a sense of the action and the vision of the size and the scope of the thing, and he also gets down and in touch with the very very essence of what is going on with characters, and he does it extremely well.
