- I had absolutely no objections to the Spock/Uhura romance thing. I was all for it. Unfortunately it just didn't do anything because of how rushed it felt.
The whole movie's a little rapid fire. I thought the relationship worked fine, but YMMV.
- And furthermore, why didn't she step in-between Kirk and Spock when Kirk was berating him? This guy lost his mother and his entire planet to a mad man.
Everyone there knew well enough not to get involved. That scene was clearly between Kirk and Spock.
I would honestly like to know why she didn't intervene like Bones did earlier.
It'd make the one time Bones intervenes redundant. Bones needed a scene where he had a spat with Spock, because honestly it's one of the most iconic things from the series. And if she had intervened they'd be going over the same ground.
Really, they're balancing the character screentime here. Give Uhura more stuff to do in addition to what she's already doing, and Bones/Sulu/Chekov would all become further marginalised. They don't get the character stuff she does, but they do need to justify their top billing by doing
something, damn it. TOS has never been an ensemble, but the 'little people' do sort of matter and arguably no
Star Trek film has been as conscious of that as this one.
The only thing about Uhura's depiction that struck me as could even be construed as sexist is that when the boys - Kirk and Spock - go off to save the world, she's the one giving Spock a farewell kiss and staying behind. Alright, it made sense to me - even with her expanded role, this is a Kirk/Spock film, not a Kirk/Spock/Uhura film.
As for giving Uhura a new job, well, she's
Uhura. 'Hailing frequencies open captain', indeed, for better or worse it's her signature role. That said I do hope she remains very prominent in the film series - Saldana's definitely proven she's got what it takes to be a leading lady with this first picture.
To put this another way: Yes, she's the only lead female role. She's
also the only lead female role, which is doubtless why she has been given the expansion that she has. Movies these days do tend to not get by on
Lawrence of Arabia depictions of women, basically.
