The argument is a bit semantic. Which is my kind of argument.
The franchise would still be making money right now if Abrams hadn't come along. OTOH, it would also be in the process of dwindling; the primary fuel of Trek was the screen product, without new infusions there's a limit to how long all the tie-in merchandise and literature and comic books can keep spooling itself out and retain profitability. "The franchise" proper was not "dead" when Abrams signed on, but its heart, the
screen franchise, had most certainly stopped pumping. It was just a matter of time before the rest of the body got the message.
Abrams' films certainly
reanimated public interest, which is no doubt what they were meant to do. I don't believe they've "breathed new life" into the franchise, which right now is kind of a Frankenstein's Monster suspended in an awkward place between life and undeath;
Warped9 is right to point out that it seems to have led to little in the way of anything new in the way of real money-making add-ons beyond the short-term box office and BluRay-DVD cash infusions, and given that it was all pitched to an entirely casual audience that's not surprising. (Moreover as film quality goes, they're not the kind of super-compelling product that has any real chance in the "long game;" regard for the AbramsTrek films seems to be decaying after the waves of studio-managed hype that launched them.)
So my vote is that AbramsTrek put the franchise back in motion again -- which is important -- but that claims of its "resurrecting" the franchise are overblown.
