Instead of going back to revamp the franchise, I think they should have done a Starfleet Academy series set after Voyagers return.
Stop right there (because the rest of that post is nothing more than fanwankery).
Creating a new tv series right after Enterprise got cancelled would have been the worst thing they could have done, no matter what the show was about. People were sick of Trek at that point, and CBS was sick of producing it.
No, the Abrams TOS reboot movies were totally the right way to go to re-energize Trek; not some academy tv show that hardly anyone would have watched.
