The script:
"INT. ECLIPSE DESTROYER - BRIDGE
A massive navigational bridge dense with FIRST ORDER CREW."
"FIRST ORDER TECH
Just the bridge crew, sir. The rest
are on dock leave."
Again, it was sitting at space dock, it's not like it was ready to fly out and had a skeleton crew. It had much much less then that. If the navigational bridge is all that is required then the ten of thousands of people that work on the hundreds of other decks on a eclipse don't really have a job with regards to operating the ship. I don't like that idea.
The script (some bolding added for clarity):
---
LEIA
They’ll kill millions. I’ve seen it. It’s too reckless.
POE
Resistance is reckless! Passion is the greatest weapon we have!
Poe appeals to Leia. Their history together laid bare.
POE (CONT'D)
The Rebels fought the Empire and won. You showed us it could be done. But that was your war. This one’s ours. Let us fight it.
Leia looks out at the Resistance Fleet. Young. Ready.
LEIA
Set a course for Coruscant. Ready all weapons and attack ships. This is a full assault.
---
You are leaving that they were forced to leave their base because Poe brought a Eclipse-clas star destroyer there.
The script:
---
Kylo reaches out. The stone slab slides off and falls to the ground with a THUD.
He looks down into the well beneath the temple, deep into the heart of Mortis, eager for his reward...
It’s EMPTY. Nothing. A hole in the ground.
KYLO
No...no....
Kylo searches the rune-covered walls for answers. He finds only arcane sculpted faces looking down at him.
---
"LUKE (VO)
This is where the dark path leads.
An empty tomb.
LUKE SKYWALKER’S VOICE. Haunting his nephew like a spirit.
KYLO
And where did your path lead?
You’re a ghost.
LUKE (VO)
I know what you’re searching for,
Ben. Your Master promised you
strength, but you feel hollow.
KYLO
Soon I will be more powerful than
any Jedi. Even you.
LUKE (VO)
Are you sure?"
"LUKE (CONT'D)
Beneath the Temple of Mortis lies a
power beyond anything the Jedi have
ever known. If Kylo reaches the
Temple, all we’ve fought for will
be lost. You have to confront him."
These are the passages I'm referring to, whether Kylo ultimately fails to life up to Luke's fears or not doesn't retroactively improve Luke's characterisation here.
I can think of at least a couple of other reasons someone may not involve themselves in a losing battle.
So can I. All the same, having established that not a single person is willing to help, not one single head of planetary government, ship captain or even person manning a communications panel in the galaxy being willing to even respond with a message to remorsefully decline, the story should be about how the galaxy moved past this state of affairs, not skip to that substantial problem being overcome off screen.
In fairness, that is something that began in "The Last Jedi." For that matter, the Resistance mattered to at least some people not already part of it there too.
How? Only the last few handul of Resistance survivors and the First Order witnessed Luke's final stand. And only the Resistance and Kylo are aware that Rey was Luke's apprentice. Did the crew of the Millenium Falcon do nothing but go around orating Luke's demise and dropping the news that he trained an apprentice for a week before he died throughout the galaxy for months? If that is how hope was restored the galaxy, SHOW us that instead of skipping to that being the case, cause it's not exactly the natural progression.
The script:
"The Dropship touches down in a canyon of white and blue sedimentary rock, kicking up a storm of silver sand.
STORMTROOPERS shield their eyes as the craft spits out a new batch of MIGRANT WORKERS from all corners of the galaxy--aliens and humans submitting to the First Order in exchange
for safety and a scrap of food."
I know you've seen the other movies, but I guess I should add extremely hostile species that doesn't speak Basic to the Tusken Raiders description. There are millions of species that have spread throughout the galaxy and are ubiquitous in any population center and thus a common sight and useful as a disguise. The Tusken Raiders are not among those species but are iconic to us because the movies take place in no small part on Tatioone, a sparsely populated back-water desert planet that the average citizen of galaxy, like Rey or workers on Kuat probably wouldn't even have heard of much less recognise a local from. But it's recognisable to us so it gets the edge on being Rey's disguise. That's dumb fanservice in my eyes.
The script, I'm told is rather faithful to the summary of it, I'm led to understand.
