Hi pontalba, I have been watching the original series too. Uruha was indeed completely convincing as a ships officer with a job to do, and she had that dignity. I remember Whoopie Goldberg in an interview saying what a huge impression the character of Uruha had on her personally, with so few black role models in TV to look up to . I haven't seen this film, but in the first film what did the new Uruha bring? Sex and a pretty face. I definitely DO think there was a dumbing down and selling out in her case. Is there any role model for a young teenage girl (of any colour) to look up to? No.
Both Kirk and Spock have really impressed me re-watching the original series, at least when an intelligent writer is behind the episode. Spock's character is really corny and says the most stupid things in the first episode (Where No Man Has Gone Before) but by the second episode (The Corbomite Maneuver) his logical thought processes are both more apparent and yet more understated and subtle. Which is the mark of a good actor to convey something without being obvious.
