She had none of Uhura's deliberate sensuousness but in fairness to Grace, that wig was really heavy so her poise and apparent uptightness could have been partly due to that.
NuUhura's apparent lack of a playful sense of humour is the least appealing thing about her so far.
I think that blaming a costuming prop for Whitney's poor execution of the character is a poor excuse...sorry
As far as NuUhura is concerned (goodness some of you folks are really hard on this movie and new cast), if she seems to lack the playfulness of Nichols, well that might have to do with the fact that she is playing the character when she is much younger,very concerned with being taken seriously, and maybe isn't as confident about herself as she would later be when Nichols plays her. In other words, in TOS we see a more experienced, calmer, cooler officer who can let her harid down a little; and in the evil Abrams movie we see a less secure, younger Uhura who is more preoccupied with showing what she can do and proving herself.
It makes sense, people tend to mellow out more at work as they become more confident about their abilities and more comfortable in their work environment.
I think that inventing a backstory for Saldana's poor execution of the character is a poor excuse...sorry
