With regard to the OP question, now that the newness of it is starting to wear off, yeah, retrospect is making me feel like there's some things that it would have been nice to see followed through on.
I love TOS crew, while at the same time was okay with and interested in seeing how they developed differently in an alternative reality. I liked the sense that because they met each other in different ways, how the ensemble relate to each other may have echoes of what we remember in the old show, yet have alternative nuances. I liked Uhura's expanded role, didn't see her as a replacement of "the big three", it felt like her dynamic could have made them more of a big four (except we don't have a strong sense of her rapport with Bones). I liked her sassiness with Kirk, the sense that she could keep him honest by calling him out sometimes. She has a self-sacrifice moment for Kirk in Beyond, separating the Saucer section, but I think the movie could have taken a moment to have at least one more character beat between her and Kirk to show that, while they've achieved that mutual respect, she is also willing and able to give him sass.
It's unfortunate that Uhura and McCoy have not interacted yet, especially when their dynamics with Kirk and Spock sorta parallel each other a bit. Wasted potential for a big 4 indeed.
I, for one, liked the Spock/Uhura/Kirk trio more than the 'trying to restore the old Kirk/Spock/McCoy trio back' from star trek beyond because it gives me different dynamics beside the bromance; I still think it works better for this trek.
I know that some fans wanted more Mccoy and the original trio back, but I don't see why the potential of the new things must be constantly wasted because of
nostalgia, and why we must insist things are the same when they really aren't.
The Kirk/Uhura/Spock dynamic is well liked and considered the 'image' of this trek now, along other aspects that make it a separate thing.
I don't think that having an all male dynamic is a wise move in 2016. Trek may come cross as 'old' and limited and conservative compared to other things, and I really don't see how that would be a good thing.
It's not that I hate the original trio, but it's 3 dudes and it's literally having
only male friendships over and over and over. In a way, I have to settle for that in tos and I accept the limits of the 60s not making it possible to have other things, but I'm not willing to give them a pass in 2016.
I think the trio with Uhura makes more sense in this trek,
anyway. The way Uhura does show Spock that there is good in his human side is a different approach, and more enganging to me, than trying to replicate the love-hate relationship between Spock and McCoy in tos, that is something that, to some extent, we already had with reboot Kirk/Spock anyway. If Kirk and McCoy are Spock's opposites, Uhura is that character who is NOT his complete opposite and she challenges him without necessarily having to treat him as a weird alien who needs to be either attacked or placated. She's, in a sense, what McCoy is for Kirk with the added layers of a romantic relationship that is something the characters didn't have in the old thing. I honestly like that the introvert nerdy guy is the one who gets to have a stable relationship in the story.
The banter with McCoy can be funny but it doesn't really add, for me, anything new to this Spock and might come across as a bit forced too for a Spock who is, after all, different and not so on denial about his human side and feelings like Nimoy Spock was.
If turning Spock into an impersonation/parody of tos Spock will be the new modus operandi in future movies, and the price I have to pay for the writers to find pretexts to give him banter with McCoy and have the 'original trio back' (and restore Kirk's original status as the one and only protagonist vs the first movie essentially making Spock a co-protagonist), sorry but I'll pass.
and I don't get
Lin honestly. He said that his movie wanted to do more with the relationships that tos
never explored, and yet, he apparently didn't understand that JJ did EXACTLY that.
So, not only he dismissed Uhura's new role, but he made it about the old tos stuff at the expense of the new.
Am I supposed to really believe that trek fans are so stuck in what tos couldn't do, that we project tos on the new movies, characters and dynamics to the extent we can't even notice it when some things are different?
Because, I mean, there is a level of headstratching obliviousness in some of the stuff Lin and Pegg said about these characters. They don't even seem to understand how foundamentally different the dynamic between this Kirk and this Spock is, and the consequence of that when you want to pretend the old trio dynamic is the same exact thing it was in tos - in spite of these movies literally never giving to these characters those 'roles'.
Maybe to some it doesn't matter either way but it's a problem for me.
It's also a problem for me that in 2016 it seems like you apparently couldn't give more screentine to Karl Urban and explore some spock/bones bromance without having to break Spock/Uhura up and keep her away from both him and Kirk for 90% of the movie.
and yes, the fact they didn't completely ignore her and her dynamics doesn't make me give them a free pass when there was such a deliberate effort made to write her out of the trio and restore all things old. They didn't even
attempt to develop an interesting dynamic between Sulu and Uhura.
Having Uhura and Spock broken up throughout the movie, opens the possibility that the next movie will drop the relationship, or give us an impression that they start spin around in an on-again, off-again romantic relationship; that won't feel like progress to me. OTOH, if they show Uhura and Spock taking Saavik under their wing as a young child and building a family together, that would follow through with Spock's feelings of responsibility towards his Vulcan people, and move him forward with Uhura.
If writers are so obsessed about dynamics being in peril, they can add drama to the bromances next time. Just challenge k/s or Kirk/Bones with a misuranderstanding or something they fundamentally disagree about and questions their friendship. Imagine if the actors had to tease about a movie where the guys are not friends anymore...fans take those dynamics so for granted that it seems like nothing new can be done with them..
replying to your point: I'm not holding my breath, but you'd think that in a fourth movie it's reasonable to believe that now the writers should maybe feel like trying something different than giving the romance more 'will they won't they' angst fest AGAIN. Dropping the relationship would be overkill and unnecessary at this point and, after all, their relationship is here since the first movie and they have many fans that are still hoping to finally see them do something a bit more with it and its potential.
It also would come across as if only Spock's relationship with a woman can be sacrificed all the while his friendships with the dudes are considered a given and untouchable by the creative team.
People who like these movies and the new dynamics don't deserve less consideration and respect than the fans of the old tos dynamics that the creative team constantly makes a point they want to make happy.
At this point, just show them being a couple... that would be a different approach and more 'new' than breaking them up again or giving them relationship issues. It's not like these characters are starving for threats that challenge them outside of their dynamics, anyway.
Also, he is a (half) vulcan and they are a couple since.. 6 years!? maybe they could start to talk a bit about the uniqueness of being with a vulcan, and a human/vulcan relationship, beside the whole 'he has a hard time showing his feelings'. We get it, but there is more to the vulcans and Spock than that, at this point, cliché.
If, like I read some suggesting, the reason why they don't do more with their relationship is because they are 'scared' of some trek fans still.. well, that's beyond (no pun intended) ridiculous. I mean, JJ&co already did the bold thing putting them together in the first place, and people for the most part embraced it already, outside of some who had a nervous breakdown over Spock kissing a girl and liking it. After 3 movies of them being a couple, it's a tad too late to get self conscious about it and keep things 'tos safe' still.
