Egads, already to page two and no one has mentioned Star Trek: Into Darkness?
If there was ever a "villain" who was justified in his actions it was Khan. Everything he does in that movie is done with the goal of either saving his crew (who he considers his "family") and getting revenge on the Section 31 boss who basically had been using his crew to extort him into being his puppet for so many years.
In contrast, Kirk & crew seem like little more than a bunch of self-serving teenagers out to impress someone who, it turns out, is sending them on a suicide mission for his own personal agenda.
And even when they figure out that they've been given the shaft they are still naïve enough to think that the rest of Starfleet Command wouldn't just dump them all into a vat of lye and say their ship was lost in a training accident in order to cover up for all of Section 31's embarrassments. Let's be realistic: When someone catches someone in power lying, who gets in more trouble: The person in power, or the person who catches them? Spare me the "utopian" vision - in real life Kirk & friends would have had black-bags over their head the next day and ended up blamed for the whole thing. It's not like Section 31 was just one man & one ship, after all.
Also for the record: Yes, the dreadnaught crashes into Earth and kills untold thousands of people. It does this because Spock sabotaged it with the trick torpedoes, and any half-way competent investigation would place the blame on his shoulders for recklessly blowing a hole in said dreadnaught while it was still in Earth's gravity well, full-well knowing that it would crash into the planet somewhere. If anything they were lucky the engines didn't explode on impact. "Criminal Negligence" does not begin to give justice to the folly of Spock's actions. Which goes perfectly in synch with the above as an excuse to make Kirk & friends disappear.
Bonus: Notice how in the film they tried to retcon Khan's backstory into making him out to be a mass-murderer during the Eugenics Wars? In the original "Space Seed," however, they clearly said that Khan's rule was the most enlightened of all the "tyrants" of that era, noting "there were no massacres" under his rule.
And finally, oh yeah, they said that war with the Klingons is coming. Well even if it wasn't true before it certainly would be after Kirk & friends basically raid the Klingon capitol and wiped out an entire company of their soldiers. Luckily Earth is prepared, having finally finished their new top secret... oh... ummm, ooops? Well don't worry, we've still got the designer... oh... ummm, crap he's frozen again? Well certainly the destroying of half of the city and Star Fleet Academy won't cause any delays in getting the rest of the fleet ready for battle, right? Um, right?
So basically the epilogue of the movie is "Earth Conquered by Klingon Empire and it's all Kirk's Fault."
