I prefer to think of the new movie as something that isnt Startrek, something that is something else pretending to be Startrek, like if some factory puts a fake brandname on its shoes or shirts, like if somebody should just go out and make a independent starwars-movie without the approval of George Lucas and Lucas-arts.
No, that's called fan fiction. This was made by Paramount Pictures, the studio that owns Star Trek and has the exclusive right to make more of it. This is more like George Lucas making the Star Wars prequel trilogy. Whether you personally like it or not, it's still the official, approved continuation.
Think about how extremly silly it was..... Kirk became the captain of the best ship in the federation at a age of 24, without finishing starfleet,
25, actually. And he was apparently near the end of his Academy tenure, since the Kobayashi Maru is evidently a test taken near graduation (since Saavik was in a red cadet's turtleneck when she took the test in TWOK but was in a white command turtleneck mere weeks later in TSFS).
the noble Spock stops being noble, and tosses Kirk out on a dangerous alien planet where he would have died had he been more unlucky - why?
The escape pod's computer specifically told Kirk that the local conditions were unsafe and he should stay in the pod until help arrived. It was Kirk's own fault that he foolishly ignored that advice. I mean, what was he planning to do? Just wander aimlessly until he froze to death? Leaving the pod as Kirk did is the most incredibly stupid thing you could possibly do in a situation like that. At least Spock's flawed judgment can be justified by the fact that he just witnessed the death of his own mother and his entire planet.
