I want Trek to not be afraid to play the "smart" card this time. There needed to be action and effects to get people in the theater the first two times. Three can have that too, but don't dumb it down. Slowing things down and focusing on character instead of plot points would be nice as well.
Include the Klingons, but don't include any other homages. None. No in-referencing old movies or episodes. No Spock Prime.
