Finishing the Academy in three years would seem to be indicative of a hard worker. But what do I know?
He didn't finish the academy in three years. He bragged that he would, jump cut to "three years later" and a few scenes in he's about to be kicked out for dishonesty. No evidence of him successfully completing a four-year program in three years.
A starship captain that seemed to have an eye for talent.
A Starfleet captain who, during a time of extreme jeopardy to not only his ship and crew, but to Starfleet itself (remember they warped into Vulcan and most of the fleet was already destroyed by that point), and to the home planet of at least one founding member of the Federation, decided to risk it all by picking the single least qualified person on the ship to be second in command. The movie was written with a happy ending. But if this were in any way to have played out without Kirk needing to end up in that chair, there'd be a whole lot of dead people on that ship. The problem is the progression doesn't make sense. It all comes down to destiny and bad writing.
I thought it was a clever way to spin the new universe off of the old one.
Using Nimoy as a guest star was great. Changing the tone of Trek from one of hard work, dedication, and relying on your team to accomplish goals into one "you can all go to hell, it's my DESTINY" wasn't.
The Kirk's of both timeline's cheated a bit. So if you see that as a bad trait in one, it should automatically be seen as a bad trait in the other.
Right. And what's the substantive difference between them? In Prime it was a throwaway line that hinted at and nicely fed into the whole death of Spock thing. In 2009 it was a plot point that took up 10-15 minutes of the film. It's one thing for someone to tell you they cheated 20 years ago, it's something different entirely to watch as someone cheats with an arrogant smirk on their face right in front of you. The first is barely a blip, the second make you want to flush the asshat out the nearest airlock.
Knowing with utter certainty that he was right and that everyone around him was wrong no matter what? The drive to prove that he was right no matter the cost?
Well now, that's a strategic selection of quoted material there. Here's the rest that you left off...
Knowing with utter certainty that he was right and that everyone around him was wrong no matter what? The drive to prove that he was right no matter the cost? Those last few aren't positive traits, I'm afraid. Perseverance and sticking to your guns (to a point) are positive traits, knowing with utter certainty that you're the only one who is right in the universe and being willing to risk the destruction of your home planet to prove it... not so much.
because it's relevant to...
Ever see Star Trek: The Motion Picture? The Search for Spock? Quite a few episodes of TOS? Kirk gambled many, many times that he was right. It was part of what made him a memorable character.
TMP. Kirk, a captain with years of experience, bullied his way back into the captain's chair and pushed aside a newly-minted captain with far less experience. TSFS. Kirk asked his friends to help search for their other dead friend and stole a ship. Not really on par with the Federation is in jeopardy so let's give the keys to the flagship to the single least qualified person on the entire ship.
Further, what's the difference between Kirk in TOS and the TOS movies compared to Kirk in Abrams' film? In TOS and those films the character has earned the trust of the crew and the audience, so when Kirk Prime makes similar decisions you know he probably knows what he's doing and the crew trusts his decision. In Abrams... not so much. If anything it's the opposite. His character at that point in the film was the least qualified to be in charge of anything, much less the flagship in a Federation-wide emergency... which brings it back to destiny. Which is the opposite of what Trek has always been about.
Look, I'm all for character arcs and development, my issue isn't with nuKirk as a more... eccentric version of the Prime version per se, rather, I take issue with the fact that it all comes down to destiny that puts a clearly inexperienced and apparently incompetent academically suspended third-year cadet in the role of First Officer, after which that character proceeded to emotionally manipulate a genocide survivor to seize control of the Federation flagship. That command structure is pure chaos. At least on Klingon ships you have to fight well enough to beat the person ahead of you on line. At least that would be somehow earning the post. Destiny... not so much.
