characterization, intelligent writing, social commentary, stories that mean something, characters that have depth and diversity and who work together to bring a round sort of holistic wholeness to the ensemble...
and he replaced all that was good with Star Trek with everything that makes a summer blockbuster movie: tits, explosions, speaking in cliche easily-memorized phrases, more explosions, an easily hate-able bad guy with a motivation that's so trumped up and unthoughtful as to be ludicrous and who is so one-dimensional and vapid even Carrot Top looks like Plato next to him, more explosions, some more tits, and in the end, a lot of explosions and the tits go to the winner.
Uhura had a place in Star Trek - the real Star Trek - because the writers back then wrote intelligent (most of the time), thoughtful, introspective philosophical pieces in which a black woman communications officer could actually have a role that was meaningful, inspired, nuanced, and intelligent.
The new Star Trek - which is really just Die Hard In Space (or maybe Lethal Weapon in Space) - unfortunately has no place for an Uhura, and the writers have no concept how to use a woman - any woman - but especially not a woman like Uhura, except in the action-movie cliche role of 'tit-bringer.'
Sad, but that's what Trek is now, I guess.
* please note, my use of "tit" here is not me trying to misogynist, but me sarcastically using the language/symbology that I feel the writers and producers of this shitfest, and other similar action-at-the-expense-of-story shitfests, are using.
