What is it, then, that appeals to to them? I know I was nostalgic--the movie made me nostagic for a time before I was a trekkie, when the stupidities of this film (which dwarf those of TFF, even, a movie I loathed from the moment I saw it) would have sailed over my head. Likewise, I dug the action set-pieces, which many have praised. Indeed, this movie is poised to be the hit of this summer, based on those set-pieces and the fondness a great many people had for TOS before it got bogged down in an accretion of canon from 10 movies and four spin-off series. Hell, Abrams has as much as said that that's the movie he set out to make.
If you're gonna take issue with the argument, it makes more sense to take issue with the part that seeks to dismiss the appeal of nostalgia and of well-constructed action. If not, then tell us what you think people are responding to. The buddy movie cliches? The re-hashing of Spock's mommy issues? The TOS easter eggs?
(And contending that a movie can be a financial success and a--subjective, of course--artistic failure is not moving the goal posts. Titanic was a horrible movie, The Bridges of Madison County a horrible book yet Vincent Van Gogh sold one painting in his lifetime.)
