In the sequel I want to see one of two things. Either:
A) A plot about discovery or some unknown thing or exploration (think ST 1 or 5 but actually done well).
or
B) Some badass Klingons. The TOS Klingons are really simplistic baddies that are against the Federation for no real reason, but in TNG they really expanded upon the race and gave them the sense of honor, the ridges, weapons, culture, etc. So take the fleshed out Klingons and make them the bad guys again. And make them tough, not comedic like they were usually portrayed in the movies (ST 1, 5, 7, 3 was iffy, they were kind of badass but Christopher Lloyd was the lead Klingon).
It would be cool if they did a story with Klingons that are actually working for the Klingon Empire. All the times that Klingons are encountered in ST, they're always kind of working on their own and trying to kill Kirk for personal reasons or just for fun. So instead of a "Starfleet and Enterprise vs. some Klingons" story, it'd be cool to see a plot about "Starfleet and Enterprise vs. some Klingons and the Klingon Empire."
What I don't want:
A) Time travel. They shouldn't do another time travel plot for at least 20 years.
B) Khan. The character has no history in the new timeline. Wouldn't really make sense, plus it's been done and I want to see new stories, not just remaking old stories.
C) A villain storyline. Except Khan, Star Trek villains are always pretty lame. It's always some random guy who has a beef with Kirk or Starfleet and they have to kill him. Think outside the box, guys.
