It might not be to much of a dream. First Trek got Abrams who is a nerd God though he is little like George Lucas and Roddenberry and you sometimes think he doesn't deserve that status. If you then get Tarantino then it opens the door up for other big name talent to be willing to maybe do a Trek movie. No longer do you have to hope a tv guy and a unknown like Harve Bennett and NIck Meyer can save the day. If Tarantino makes a movie of his usual caliber it can change everything for the franchise.

Then again, Robert Wise was probably the biggest name director to ever helm a Trek movie, and yet the tv guy and the unknown arguably made the better Trek movie. (Yes, I would argue that directing THE SOUND OF MUSIC and WEST SIDE STORY and THE DAY THE EARTH STOOD STILL, not to mention editing CITIZEN KANE, trumps directing PULP FICTION.)
And I say that as somebody who really admires a lot of Wise's work.
