Well, it is a trite thing for J.J. to say, but yes, it's also a necessary thing to say.
No, it isn't necessary. The 09 film succeeded. The public was satisfied and the fans didn't storm off. There is no need to say that it is not made for fans
rather than saying it's not made
just for fans, a locution which gives the fans some love too.
If "Star Trek" is going to continue to be successful, it needs to regrow a fan base.
Again, the '09 film succeeded. There is no need to jettison or disavow the existing fan base in the hopes of growing a new one.
Fandom is unlikely to ever be the same, too. It will be a more casual acquaintance with Trek.
So, what is the point of attempting to regrow the fan base if there will never be another fan base? Why go to so much trouble for casual acquaintances who don't really care either way?
___________________________
The expedient hyper-adaptationalist argument (i.e., the present stewards of the franchise should
only concern themselves with raking in $$$ and pleasing new viewers, because Trek must survive no matter what!), is rather ridiculous;
the very reason one would even care about whether Star Trek survives, would be because one believed there is something there worth saving, that there is something special about Trek. But to try to mindle$$ly and pragmatically save Trek without any concern about its "specialness" undercuts emotional warrant of the argument. If what were saved only shared a passing resemblance to the former stories, why worry about saving it at all costs? Who cares if Star Trek survives in name only?
The preceding is NOT to say that this is what the filmmakers are doing. They have worked hard to honor the past, recapture some of the magic, and create elbow room for new stories. Rather, this criticism is directed at blind apologists who keep arguing that no price is to high to save the franchise.
