I know I'm likely alone in this view, but in spite of Trek's (previously) languishing state, I always considered it above the fray in many respects. It had a certain integrity because it had not surrendered itself to the lowest common denominator.
Bullshit. Star Trek has always had episodes and scenes that pandered to the lowest common denominator. Orion slave girls? Kirk seducing beautiful, half-naked women? Planet of the Nymphos (aka "Justice")? Kira's uniform? Seven of Nine? T'Pol? Everyone in their underwear in the decon chamber? T'Pol's nipples in "Broken Bow?"
The idea that Trek has ever been a high-brow franchise is a ridiculous myth.
Of course, it has now done so unconditionally with this new film. Storytelling is out and attention span driven action sequences are in.
Absolute nonsense. Storytelling hasn't been put aside, it's just that this is one of the few Trek films to actually use the action-adventure genre properly. Are there action sequences? Yes. Is it fast-paced? Yes. There's also a wonderful story about two guys learning to put aside their differences and learn from one-another. To pretend that one doesn't exist is absurd.
I think the brand has been severely damaged,
The brand has not been damaged, it's been brought back from the dead.
