I get that the movies are about growth -- Kirk's growth, principally -- but there are better ways to explore that kind of evolution than promoting a cadet to Captain (as opposed to just giving him a commendation) and then watching him whine about losing his ship because his first officer, if you can believe the audacity, told the truth.
Agreed, that especially felt like the filmmakers expected the audience to sympathize with Kirk just because he's the star and he was the star/protagonist in the other timeline and maybe because he's human and purportedly charismatic so he must know better than either a Vulcan or the older, drier admirals at headquarters.
