The romance with Spock is dumb but otherwise NuUhura is an OK character. She's just given far too much focus, which is a bit annoying as just about everybody prefers McCoy and Scotty.
I think the issue we have is that Star Trek has never really been a loud, dumb, adrenaline ride. The writing is now an afterthought, when it used to be the driving force of the series. I actually like
the stagey feel of the TV series, and feel uncomfortable seeing Star Trek resemble Bayformers.
