Without indulging in anything else I would like to see in the next Star Trek movie, I will say this. I love me a good space battle. The battle between The Kelvin and The Narada is the only showdown worth mentioning in the reboot, and that was over before the opening title ran!
Give us a proper showdown between two interstellar powerhouses that make the Borg battle in First Contact
look like a minor skirmish.
