Wasn't this like the sort-of theme of the third trilogy? The Jedi tried to eschew attachments to prevent strong emotions like anger, jealousy, fear, and hatred. But Luke realizes that the Jedi were wrong. Being connected to other people is what the Force is all about.
At least, I think that's what they were going for when the franchise sat on its own collective balls.
From the corner of his eye, he saw Threepio stiffen. "I hope I didn't offend you, sir," the droid said anxiously. "That was certainly not my intent."
"You didn't offend me," Luke assured him. "As a matter of fact, you might have just delivered Ben's last lesson to me."
"I beg your pardon?"
Luke sipped at his drink. "Governments and entire planets are important, Threepio. But when you sift everything down, they're all just made up of people."
There was a brief pause. "Oh," Threepio said.
"In other words," Luke amplified, "a Jedi can't get so caught up in matters of galactic importance that it interferes with his concern for individual people." He looked at Threepio and smiled. "Or for individual droids."
"Oh. I see, sir." Threepio cocked his head toward Luke's cup. "Forgive me, sir... but may I ask what that is that you're drinking?"
Hey TLJ was good. RoS…yeah I definitely try to forget that exists. Palpatine flying around on the weird tentacle arm thing made me audibly groan and roll my eyes so hard they nearly fell out.
I still hold out that Rey and Ben should have switched sides in that movie (at least temporarily), because it really would have let us explore some cool ideas that hadn't been done before.
But I do agree that the "letting go of the past" thing was a really great theme to have as the core of the movie, because it shows that Luke was falling right into the same mindset that the Jedi order had and was their downfall. But this time, he didn't let the "old ways" become his downfall.
I don't think they should have switched sides but make their own thing all together, grey jedi style. Maybe not even as allies but at least something new. Kylo was clearly never as into the whole "dark side" stuff the same way Vader was and Rey had barely any association to the jedi, except for being force sensitive.
Would this have been better? Maybe, but at least it would have been DIFFERENT from just rehashing the OT. I'd rather see something I like try and fail that to not try at all.
That definitely would have been interesting and there were a lot of scenes in TLJ that hinted Rey was exploring some dark thoughts. Too risky for the mouse I guess.
