South Park mocked J J Abrams heavily but I don't see the problem with him. "But TFA was basically Star Wars Episode 4 rehashed"
No it wasn't
Abrams knows what to do, in technical terms, to make the audience feel what he wants them to feel, in any given scene, and hence throughout the film.
The problem is his failure to have it meaningfully connect to the narrative.
A good example, in Into Darkness, the eye candy chick's father is killed, and she's cries about it. So sad.
But...then she's perfectly fine 5 minutes later, and that scene is never mentioned again. It has no impact over the narrative, Abrams just used it for a sad scene.
Or with Cumberbatch's line: "My name is....KHAN". Intimidating scene! Close up, Cumbabatch with the base turned to 11, and he's wrested complete control of the situation from Kirk despite being locked in a prison cell. But...why should his name matter to Kirk? It should get a Starlord response (which I think that scene was intentionally satirizing btw), but Kirk treats it in all serious. Again, the narrative is ignored because Abrams has the momentary effect he wants, and that's all he needs.
My experience with Into Darkness was someone only vaguely aware of who Khan was- that he was some sort of badass that killed Spock at some point. I'm not a Trekie. So the film actually worked for me, since Abrams missing what made the character threatening didn't matter, and I suspect the film was made with the presumption that most of the audience shared my disposition.
So yeah, if you're doing a reboot and want to get something off the ground, Abrams is a fine choice. Then let someone else come in and build into a narrative. But for wrapping up your series? I don't see this ending well. I really don't.
TFA is well made and casted as ****. JJ is good at that. But man is it ever a giant waste of lore potential.
This seems a giant YMMV. I've talked to people who simply don't care that nothing is explained. Good for Disney and Abrams, they bet the house that they could make bank doing so, and boy did they make bank.
Because they wanted to setup the same dynamic as the OT. The good guys are a small rag tag group fighting a big massive opposing force that has TIE Fighters, Star Destroyers, Storm Troopers and a big mega weapon.
....OK?....
I heard that in regards to Trevorrow, the directors actually have quite a bit of creative license. The quote I remember reading...somewhere was "(the directors) have a huge room to work in, they just have to stay inside the room."
If it's similar to Marvel, which it (probably) is, directors are allowed to do anything they want as long as it can be easily retconned out of existence- which is to say, nothing they can do will really matter. It's a brilliant formula, you let good directors do what they want, then ignore any character development in the next installment.
This is why Tony Stark pinballs between daddy issues to learning to be a team player to literal PTSD to guilt over his actions to mommy issues to daddy issues (but this time I'm the dad!).
