The new characters only had a measly two hour movie to show what they had, so of course we haven't got a good read on them yet. I wish Star Trek were back on TV, where we might get more than tidbits from anyone but Kirk, Spock and the enemy du jour. But even what we got of new Uhura, she seemed far more assertive and goal-driven than I ever noticed from old Uhura. I appreciate her strength and intelligence, and find it plenty "endearing," though I think "worthy of respect" is the better description. She isn't supposed to be a tribble.Its true she should have been used more extensively but even if it was only one scene, that was enough to prove she is capable of being "active". It seems like we are at cross purposes here, however nuUhura didn't seem to do very much either and little that was action oriented. So I'm not sure the character was changed that much. A bit more 'tude is all really. Worse, I didn't find her version of it very "endearing".
Non-ultra-serious Kirk is a non-canonical Kirk. If they're ditching canon, why not just change him to suit whatever the master plan is? I'm not certain we've seen the master plan yet. I can wait, and then if no good reason emerges for the change, I'll bitch my head off about it.but as above, I was not suggesting an ultra serious Kirk, just not a rebel version.
