First, there was a lot of action. Maybe too much, but that's a matter of personal taste. What I found distracting was the repeated cycles of rising action, climax and resolution throughout the movie. All that action made the conclusion seem like a whisper by comparison.
Second, the logistics of the film make little sense. In the first movie of the rebooted franchise, the Enterprise seemed to make it to Vulcan in a matter of minutes. In this movie the situation was the same, with the ship seeming to arrive at Kronos also after only a few minutes. It didn't look like lost time that could be implied. In the TV series and prior movies some trips, like these, could take days. It appears that in order to make the story work, the question of travel time had to be glossed over or ignored.
Third, lens flare. That is all.
Having said all of that, I actually did enjoy the movie. I enjoy the Star Trek franchise but have long found it to be full of shoddy science and overly-dramatic characters. That's part of the fun. After all, it is supposed to be fun. This is entertainment, and I considered it well worth the price of admission.
