The dilemma the next creative team for Trek has is making a movie as smart as Inception was,without alienating a mass audience.
And why do you think these people have this dilemma? They've managed to make two successful Trek movies already. Why will the third be such a challenge?
Because they'll have to step up the cerebral aspect,while also preserving the action aspect .
That takes exceptional screenwriting skills,and I can easily see the creative team going too far in one direction or the other.
