Look, it can be that the film simply didn't click for some fans and that's the end of it. That's fine. It was bound to happen. Case closed, there.
The fans who were predisposed to dislike the movie and reject it outright for "not being
Star Trek" are the interesting ones. And, I think part of the problem there is they are holding this movie to a standard that over the years Trek seldom met, even when it was good. The quality of Trek has been all over the place. Sometimes there was true pathos. Other times, just corn-ball moralizing. Sometimes the story was a good comic romp ("The Trouble with Tribbles"

. Other times, the story was just plain stupid (do we reach, Herbert?). There was true drama. There was also true camp. For every "City on the Edge of Forever" or "Yesterday's Enterprise" there was a "Spectre of the Gun" or "Masks". There was TWOK. Then, there was TFF. The same crew who gave us FC also gave us NEM.
So, what the hell is "the feel" of Trek? There
isn't one other than an archtype created mostly out of a conceited Trek mythos about its qualities, not Trek reality. The realistic Trek spectrum is very wide. How can't there be room for ST09 within it? How can "Day of the Dove" fit in and "feel" like Trek, and ST09 doesn't?
