Based on what Alice Eve mentioned about it, her characterization was written both as a generational conflict and a microcosm of the rift between Starfleet and Section Thirty One. Basically, Carol had a serious conflict with her father in a relationship that was otherwise very solid and uplifting until something happened that caused him to become all warped and evil. Her backstory would be as much about her disillusionment and lost of her father figure as the evolution of Alex's jingoistic fugue, and finally, Carol's ultimately futile quest to restore him to the man once was, "and should be again."
The female character fails to do something on her own? That's nothing new for JJ's Star Trek.
That's not what I meant, seeing how Alex Marcus was tragically irredeemable (or even if he wasn't, Khan decapitated him before he could be redeemed).
I noticed that too. I think a similar thing happened with Nero's background in the first film, with all of the Rura Penthe material being removed (going deep into how he spent 25 years being tortured by the Klingons, causing an already crazy person to become even crazier). It's too their credit that the editors were smart enough to keep the character moments for Kirk and Spock in the first movie, but in STID I think they severely dropped the ball on Carol Marcus and they could have afforded another seven or eight minutes of footage to get into that a bit more.
Still, that's movies for you. If you want great character development over a long timeframe, that fits better in a TV series or a novel.
Probably because there IS no director's edition of STID and much of the deleted footage for both of those movies never saw the light of day.
She manages to penetrate Marcus' jamming and get a signal to New Vulcan.
She manages to intercept and translate the message in the first film that leads Kirk to realize the "distress signal" from Vulcan is actually a trap.
She speaks Klingon (unlike Uhura Prime) and almost manages to negotiate with them before their "Kill the wabbit" instincts reassert themselves.
She can speak Klingon, but all that does is put her in danger and needing to be rescued.
You seem to be forgetting that it was KHAN that came to the rescue, and even in that case he merely distracted the Klingon soldier while Uhura pulled his dagger and stabbed him in the balls.
About the only thing the writers can do for her character is whine about Spock and be the "action girl" with a gun. Giving her a gun to shoot bad guys with doesn't make her interesting.
Not at all. She has actually become a foil for Spock, a passionate (and compassionate) counter-balance to his cold logical mind. At the same time, when Spock looses his emotional control she plays the opposite role, stepping in to put him back on track.
What's a lot more interesting (and what you, like most people, overlook) is how Uhura deals with Spock's Vulcan aspect. She understands that he has to control his emotions, as that is te Vulcan way; in STID, this understanding is put on full display in Mudd's shuttle and is actually reinforced in the resolution. It's not just some odd thing about him that she accepts, it's something she has come to embrace as central to his personality.
Compare that with Uhura's conversation in "The Man Trap:"
SPOCK: Miss Uhura, your last sub-space log contained an error in the frequencies column.
UHURA: Mister Spock, sometimes I think if I hear that word frequency once more, I'll cry.
SPOCK: Cry?
UHURA: I was just trying to start a conversation.
SPOCK: Well, since it is illogical for a communications officer to resent the word frequency, I have no answer.
UHURA: No, you have an answer. I'm an illogical woman who's beginning to feel too much a part of that communications console. Why don't you tell me I'm an attractive young lady, or ask me if I've ever been in love? Tell me how your planet Vulcan looks on a lazy evening when the moon is full.
SPOCK: Vulcan has no moon, Miss Uhura.
UHURA: I'm not surprised, Mister Spock.
^ It seems to me that the bar is set pretty low as far as Spock/Uhura relations, but I think that their current dynamic is actually a TREMENDOUS improvement.
