I think I read a summery somewhere, and honestly while it sounded like a more logical follow-up to TLJ than RotS was, it didn't exactly blow my hair back either. Very bland, almost paint-by-numbers feel to it. Still, even with the best script in the world I'm not convinced it would have been substantially better than what we got.
While I haven't seen his full filmography, I've seen enough of Colin Trevorrow's work to know that he's really not a very good director, and has *terrible* storytelling instincts. On top of all that, word from the Jurassic sets is that that guy was very much NOT a team player, which is simply incompatible with how LF operates.
JJA for all his lack of originality and over dependence on that "mystery box" nonsense, is at least talented when it comes to knowing where to point the camera and how to get good performances from his actors.
Personally I would have preferred they just delayed the movie a year or two until they could get all their ducks in a row, maybe gotten Johnson or Edwards to come back as both of those two clearly knew how to play ball and seemed to have a much firmer grasp of the franchise's underpinnings. Alas.
Agree with all your points. But Abrams himself is also notoriously "not a team player", but obviously has far, far more clout in H'wood than Trevorrow.
