We could do with leaving behind the one dimensional alien races. It had it's day with Vulcans, but by the time the Ferengis came around, it was kind of insulting. Constantly taking an aspect of human behavior and isolating as a defining characteristic of a whole group of people, while useful to a point, wears thin damn fast. I honestly don't think that was the intention the Vulcan race was meant to have, that every alien race from then on be a stereotype, even if there's a cheap ability to use it as a commentary on life
The only character arc you can possibly get from it is "Can Character X finally break free of their narrow minded ways, in order to become an actual person?"
Maybe this is a reflection on our inability to write alien characters that are alien. We only have the human point of view to draw upon.
Literary science fiction does aliens much better than TV ever has.
