I don't know if you and I are ever going to agreeWell, I could certainly see nuUhura sacrificing herself make nuSpock go berserk. But nuKirk? Nah, that really only works when you apply the traditional TOS friendship as a foundation. I mean, I kinda' can see him let loose in a personal fistfight, but nuSpock doing the "KHAAAAAN"-yell was...distracting. I still don't see any benefits in copy-and-pasting the emotional climax of another, better movie line-for-line for a new movie, it really is one of the most baffling things in mainstream entertainment I have seen in the last 20 years. It took me right out of the movie, maybe it's because of that that I can't take it seriously. But it kinda' seems JJ. Abrams way of operating these days, Force Awakens being a beat-for-beat remake of A new Hope and all.

I don't see the "copy & paste" other than the dialog. The emotional beats are far different, Spock's reaction is one of savage pain and loss (echoing Nero as Spock's dark mirror) and Khan becomes the focus of that rage. It's not logical, it's not rational. It is pure rage and it's Spock hitting his breaking point. From a character point of view, it follows just fine from the narrative beats of 09.
I don't see Kirk and Spock as friends in the TOS sense, so i will not apply that lens. I see that as inhibiting the ability to enjoy the film, at least for me. So, I work within what the film presents, and I see all the emotional beats being set up very well within the narrative text and subtext.
