She acts as a translator when a universal translator would've done, and she beams on to a windy, high-moving vehicle in a dress to calm Spock down. Rest of the time she's complaining about her relationship problems. It's great that they made her more of a linguistics expert, which should come in handy on the five-year mission, but both come off as a little reaching to give her stuff to do.
She acts as a NEGOTIATOR, possibly the first of any such negotiation actually attempted so far as we know, and volunteers for it as a means of short-circuiting the captain's "plan," which would have started a war.
She's also not "complaining about relationship problems" she's sparking off the secondary arc of the movie, which is Spock's. Spock's trajectory in the film absolutely does not happen without her reframing the discussion in the first place. She's actively forcing him to reconsider and think about why and how he acts/reacts with people, a thought process that pays off in the last 15 minutes of the film.
C'mon with that "in a dress" thing, too: her standard issue uniform is a dress. She's not being demeaned by wearing it. Also,
she doesn't beam onto the platform to CALM HIM DOWN, but to SAVE HIS LIFE and the life of the man he's chasing as a means to save the life of the man who saved them.
That is not "basic girlfriend shit." If there's stretching, you're doing it, as a means to artificially diminish the character's motivations and actions to fit the categorization you've slotted her into.
