Trek was an old rotting corpse festering with the maggots of 40 some odd years of "Cannon
". JJ came along with his big bucks production team and gave the old dead girl some post necrotic plastic surgery, then shocked her ass back to life with a lot of space-lightning; BAM!
two weeks and 140+million dollars latter...
That being said, now to the original question...no, we would not have been able to save the script. The Trek community can't even agree on the size of the Enterprise, let alone try and agree on the details of a "great" script. This mindless fast paced flick is exactly what Trek needed in the iPod age.
