Honestly, I can't stand this whole thing. I seem to share the same sentiments, or similar ones, of Jeffries and some others. My reasons are, I think, probably what's really bugging those of us who don't like this on a deep level. It took a while to figure out exactly how to put this all into words, but hopefully it makes sense:
Basically, the characters in the series from now on are not the same characters as in the original series. Now I have no problem with new sets of characters. The problem is that they are alternate versions of the ones we know.
Trek fans have spent decades with these people, just like we have spent decades with our families, friends, and loved ones. Of course the Trek characters are only fiction, and the point is not to try to give them equal value as those real people in our lives - this would be rather disturbing, actually. One similarity, however, is important. We love our family and friends because of all of the shared experiences we have had with them. We were there for the hard times, the good times, the funny times, the sad times, and all the other kinds of times as well. We were there for their births, funerals, marriages, etc. etc. If something happened to your best friend, or to your mother, and he or she were replaced by a clone identical in every single way except for the lack of those same experiences, not only would you not love the clone, but you would probably consider it an abomination and a tremendous offense to the memory of that person who you loved so much.
That’s what these “new” characters are to those we know and love. Not only do I have, in all honesty, less than zero concern for them, but they offend me deeply. They’re not real people, so there is quite obviously a limit here (so please do not accuse me of holding fictional characters as important as real people

), but to the degree that one can care about a fictional character, I am deeply hurt and offended by these facsimiles.
Let me add one more point, which does not so much add to my argument but adds a context to it. That is, why couldn’t the franchise have been re-invigorated without changing things? The only argument I have seen from those who support the reboot is that Star Trek had grown stale and needed to be reinvigorated. That’s a perfectly reasonable stance. However, there is not a single aspect of the excitement that is surrounding this film that could not have been generated without the reboot. Have any of the small canonical changes really contributed to the film’s being highly anticipated? Was it not possible to update the visual style without changing history? Couldn’t the story be just as big, have just as big a production, and just as popular a director if it told the origins of the crew as we knew them?
Indeed, the final proof lies in the fact that the vast majority of those who are contributing to the excitement - the non-Trekkie types that so many Trek fans are so excited are beginning to care about Trek - do not even know it’s a reboot. So far as they are aware, it’s the same Trek it always was, just done bigger, better, and with more explosions and sex appeal. Yet they are still extremely excited about the film.
Thus, the biggest tragedy is that this was not in any way necessary! What is it for? What’s the point? The need?
