The movie saved the Franchise, period.
There's only one Star Trek property, one "franchise." If this movie had been unsuccessful, that would have been pretty much the end of it. Since it's worked out so well for Paramount, there now exists the possibility that CBS Paramount will at some point take an interest in producing Trek for television again.
Most people who went to see it - devoted trek fans or not - could not have cared less whether it was a reboot, a retelling, or whatever other label people want to nitpick over. They care that they were entertained.
If it tops out at three movies - well, that's three more movies than anyone had a reason or right to expect four years ago. And they they'll probably restart Trek again, just like Spider-Man or Batman.
