Being a novelist and editor, I'm sure Greg Cox is well aware of the definition of cerebral. What he is trying to narrow down is what exactly is it that fans are wanting. And he is correct, if you asked ten fans, you would get eight different answers.
Not to insinuate anything about Mr. Cox here, because I haven't read his work.
But being a novelist and editor does not necessarily denote intellect and acumen. So your argument is flawed. Novelists wrote Twilight, 50 shades of grey, Da Vinci Code, Kane and Abel, etc.
I
wish I had written
Twilight . . .or
Fifty Shades of Grey! I could live with those royalties . . .
But, yes, for the record, I was not asking what the word "cerebral" meant. I was asking what Trekkies
mean when they say Trek ought to be more cerebral or intellectual and so on.
Not in the sense of specific plots or plot devices, but in the sense of what they think makes a Trek movie or episode more intelligent--which is not always obvious.
Take "Let That Be Your Last Battlefield," for instance. Pretty much every article about Trek cites it as evidence of Trek's social conscience and willingness to handle controversial social issues. But I'm not sure it's really anybody's favorite episode or even seen as one of the truly good ones.
"City on the Edge of Forever," on the other hand, is basically a tragic love story built around an ironic time-travel twist. There's no real science or politics or social allegory in it, just a heart-rending moral dilemma. And yet it's often cited as the best and most famous Trek episode ever. Is it "cerebral"? Does that matter?
Or, moving into the modern era, what about "In the Pale Moonlight"? Many fans consider this one of the best latter-day Trek eps, because it doesn't offer any any easy answers to a thorny moral dilemma, while others dislike it because they consider it
too dark and morally ambiguous for their tastes, or because they feel it doesn't gibe with Trek's idealistic, utopian "vision." Is "Moonlight" what we consider cerebral?
This, personally, is a more interesting line of inquiry than trying to set up some sort of either/or dichotomy between "cerebral" and "popcorn" or whatever.
