Making out that Star Trek has always been stupid just isn't a valid excuse.
Lucas apologists made the same argument about the Prequels. They tore down the original trilogy by saying that any pretensions it had of being modern-myth in the Joseph Campbell tradition were just overgrown kids trying to rationalize their nostalgia.
It's a weak argument. The original trilogy is BETTER than the prequels, and at least the best contingent of prime-continuity Trek is just plain better than Trek '09.
