Perhaps Abrams was the wrong person for the job especially since he admitted he wasn't a fan, not a bad thing to say, just an odd one that must have made the marketing people think, "What an undisciplined person to say such thing! How do we spin this positively now?".
Nah, I'm betting the marketing people asked him to say stuff like that as much as possible. It effectively drove home the message that this wasn't going to be Trek made for those Dirty Trekker Nerds.
Well, it was
important to get the message out that this new movie was not Just For Trekkies Only. Star Trek was never supposed to be this exclusive, elitist thing that was only accessible to the True Believers. Star Trek is for everybody, casual fans and lifelong Trekkies alike.
And me, I'm a Trekkie, not a Trekker. "Trekker" always sounds to me like a Trekkie putting on airs.
