I think the script was really well written. They've accomplished several mechanical artistic things here:
1. They've essentially rebooted the entire future of Star Trek by allowing either new stories or allowing them to touch up/improve on already established adventures (ala alternate reality)
2. They've successfully (I think at least) typecast new actors is previously established/typecast roles quite nicely
3. They've bridged several different generations of Star Trek fans by incorporating old characters, new actors, old plots, new adventures, all under the artistic direction of today's newest special effects, and have done it well. (Worldwide: $196,875,668 to date)
4. Allowed the Star Trek franchise to proceed forward with newer and younger fans unfettered by established plot lines and conflicts.
