Fenn is against killing and doesn't want to fight(helps kill tons of his fellow troopers in his escape in TFA, seems to have zero fucks to give about killing his former comrades in this film either) Poe(abandoned BB8 on Jakku in TFA, disobeys orders directly resulting in massive losses for his own forces yet is supposed to be both caring for his own side and a good tactician) Rey(supposed to be naive and inexperienced yet routinely defeats people who should be leagues ahead of her with ease, knows the mind trick, did not have prior training according to this film now. You can't do fish out of water story when said fish is better then every friggen land creature)
This is simply escalating due to bad writing and nonsensical character development coupled with a plot that forces such out of character decisions. That's what bothers me, it's beyond badly written and it shows up constantly detracting from what should have been a great film with good actors, sets, soundtrack and effects.
1. Actually as said in journey to the force awakens book and in Aftermath: The FO stormtoopers are use to killing their own comrades. This is a affect of brainwashing which makes the willing to follow orders to the extreme, however Finn did resist that to be fair. I would also like to point out in those scenarios it is life or death for, so he
has to kill or he will be killed. Also in a deleted TLJ scene after Finn beats Phasma he tries to convince his former comrades to leave with him saying that Phasma was the one who lowered Starkiller Base's shields which killed their own supporters. While the troopers contemplate whether they should leave with Finn and Rose, Phasma guns them all down before she falls to her "death" (she is probably
somehow still alive). Finn's story arc is about him being okay with killing stormtroopers and his former comrades. Finn's story arc is about how he needs to man the fuck up and learn to take one his problems head on, and its about him finding a cause worth fighting for.
2. Poe did not abandon BB8. Poe sacrifice himself so BB8 could escape which resulted in his capture. After he crashes with Finn he escapesand cannot find BB8. He had to leave and find his ship so he could also find BB8, since he left his black X-wing at his home on Yavin 4, and by then he heard from ressitance intelligence that a group had reported thta the FO was looking for the droid which was on the Falcon, then the ressitance was alerted that if was on Takodona which is why Poe went there. Also only about 50 people died in his planned attack on the FO Dreadnaught, compare that to how many people would have died had the cannons on that Dreadnuaght had fired on the ressitance fleet. Keep in mind also that POE WENT IN BY HIMSELF aganist the Dreadnaughts tie fighters, and guns and the resistance fighters only showed up when he said that the guns were disabaled. He risked his life so that the bombers had a fighting chance. Also Vice Admiral Holdo's plan was doom to fail even if DJ had not told the FO that the ressitance was going to use the transports to flee to crait. The reason it would still fail is that the FO would detect that their is no one aboard the *Raddus* then realize the ressitance was using small ships to flee then fired. They also still would have attacked Crait and crushed Ressitance forces. Poe's plan wasnt any better, but at least he was looking out for his people. If Holdo really cared then she would have told him the plan so Finn and Rose could stay aboard and help save as many lives as they could.
3. Rey has lived on a dersert planet full or wreaked rebel, and Imperial starships. She had to fend for herself for the longest time and as we can tell by how long she has been there. She knows how to defend herself, she knows her way around starships. As for her using the Jedi Mind trick:
1. She knows the stories about how Jedi can use the force to influence people.
2. She is not the only charcter who has been able to use the force despite a lack of training. Ezra(season 1-2 Ezra), Del Meeko(he used the force to ressit the powers of Kylo Ren for a bit), Poe Dameron(He unkowingly use the force, his parents had planted one of those anicent force trees that Luke has given Poe's mother, which explain why is he such a incredibly talented pilot) and even Leia(In the shattered Empire comic she reaches out with the force and feels Darht Mauls cold presense in the old Nabbo Hanger) are all examples of charcters who can use the force despite a lack of training.
3. Anyone can tap into the force, it is just that some are better at it then others.
Now as for the Kylo Ren fight thing.
1. Kylo Ren was shot by a wookie crossbow that almost killed him. (He was punching where he was shot at boost his adrenline.)
2. He had been stab by Finn during their fight.
3. My brother mentions that he was literally using the force to slow the bleeding of his wounds(and in a more gross way, keeping his guts from falling out.
4. The Light is in herently stronger than the Darkside. Rey let it flow through her so she could muster the strength to beat EMO REN.
5. she knows how to use various mele weapons.
Aso for why Han and Leia were apart Lord Xizer. Its simpliy that Leia was being a senator then the leader of the ressitance while Han is not really the kind of person who lives a life where he sits in boring meetings or leads militaries. Han is the kind of guy who just loves flying around the galaxy not giving a fuck. And after Ben Solo fell, it crushed Han and Leia's realtionship. Also they are both just simply terrible parents. Ben Solo was also being seeked out by Snoke through the force since he was a child, who was slowly corrupting him.
and as for Luke well as i said eariler.
Actually my brother and i read the Last Jedi book guide. I can give officially a responsible answer on how the FO amassed such a large force.
So i will break it down for you:
1. The Emperor had apparently(like in legends) had sent imperials to build weapons labs, establish shipyards, and test weapons in the Unkown Regions. This gives the FO already resources to start off.
2. They took techincal documents for Imperial Black projects. This may explain how they built a weapon like StarKiller Base
3. The FO has been starting "Uprisings" in planets in Wild Space, who find that the NR is being oppressive to them.
4. The FO has been kidnapping children, and also seeking out great warriors, and ex-Imperials to join their cause.
5. They had access to the achieves of the Empire.
6. They had the Eclipse.
7. They had been treating the people they conquer or ruled over rather fairly
8. They were infitrating the NR weaking it from the inside.
9. The NR was disnfracising people at a alariming rate.
10. Arms dealers.
I now think that the NR must have been full of morons and FO spies this entire time.
As for what i think on Luke:
I think Luke would totally freak out if he saw the deaths of all these innoncent people. I mean come one people who wouldnt? How would you feel if you founf out that someone was going to destroy all you worked hard for and kill so many innocent people? Luke is human, he makes mistakes, but this time he fucked up hard. Judging by how he reacted to Vader saying he would corrupt Leia, yeah i could totally see him contemplating killing Kylo Ren. Luke keep in mind is always afraid of losing the things he cares for. Deep down Luke is just a man who is trying to do the right thing but deep down fears creating a monster. It is not bad writing, it is Luke's personal conflict. He knew what happen the last time the jedi council poorly trained a Jedi, that led to DARTH MOTHERFUCKING VADER! Luke fears that returning and he doesnt want to be the one responisble.
BTW if anyone asks
I dont support Rey/Kylo love story. I say i support more of a Rey/Poe love story.
