People are not dumb. People have taste. The era doesn't demand that movies are mindless popcorn flicks. That's just something film hipsters say.
Personally, I don't think the Abrams films are mindless popcorn flicks. But that's neither here nor there.
I think you're transposing what you want from a movie onto general audiences. It's been proven that, sometimes, people go to movies to just watch things blow-up and have a good time. You seem to completely disregard the escapism part of the movie going experience. For most people, Star Trek isn't a way of life, it is a way to escape the real world for a few hours.
Actually, I'm not transposing anything. If you read the discussion, you would understand that people are saying a cerebral trek flick could never, and would never be successful in this era. And that the contemporary audience doesn't have the ability to appreciate a cerebral trek flick in the 2010's. Basically that the trek films are as they are, because they could not be anything else.
And then you would also understand that my argument is if it's done well, you can absolutely make a cerebral, slower paced film, and it be successful.
This discussion has absolutely nothing to do with star trek tng or nutrek. It's about the conceptual ideas of what a film is allowed to be in this era vs. era's past, and how mediums affect the finished product.
