Star Trek into Darkness is the second worst movie I've seen this year, it's better than Thor 2 and nothing else.
It's completely lacking in any logical coherence whatsoever, and the narrative is extremely thin. It's just a dumb action movie. That would be ok if the action shots were good, but they are not. Man of Steel and Pacific Rim both had better action shots. The cinematography was also very mediocre -- at best. I'm not surprised given these writers.... Orci and Kurtzmann also wrote Transformers 2, and Lindelof did the re-write for Prometheus that ruined the movie. Also, I'm under-impressed with Abrams, and I don't expect great things for Star Wars VII.
I actually think STID would have been a better movie if they had removed Khan entirely, and focused on the Admiral Marcus storyline. That was a potentially great storyline and it made sense given the events of the first film, but instead of developing it coherently they cut it short, in order to have two villains in the movie.
Among Star Trek fans, STID is often considered the worst of the 12 Star Trek films, and I can sympathise. It makes no attempt to tell an actual story.
