I just got back from seeing ST Into Darkness, and I loved it! I honestly didn't seeing enough similarities to Wrath of Khan to think of it as a copy, and felt it had enough different elements to make it its own movie.
I'm guessing the Klingons will be the villains in the next movie, but I'm wondering if they'd go with a new character or bring back an old one. If an old one, I'm thinking Kor, Koloth, Chang, or Kruge.
Now with STID done, JJ can work on SW Ep 7 before going back to the next ST movie. I hope the guy doesn't like to sleep.
