The more I think about it, the more I want a proper prequel film of how Kirk really became Captain of the Enterprise. In the style of films like Love Actually, Crash or Traffic, with all the character's ways to end up on the ship told in parallel, interweaved stories.
No contrived bullshit of him meeting McCoy and Uhura in Iowa, no Spock is the programmer of Kobayashi Maru crap, no instant cadet to Captain promotion fuck.
The massacre on Tarsus IV, Kirk's adventures on the Farragut, Spock's adventures with Pike, and other stuff are interesting stories. And there would be still A SHITLOAD of room to tell new exciting stories the characters had before getting on the Enterprise.
And just for fun I want that 300 style epic Klingon tale about Klingons slaying their gods, and Kahless' adventures. R-rated, heavily stylized, science fiction fantasy epic.
