I don’t remember a lot of the exact dialogue, but Luke’s line of how “Do you think I came to the most unfindable place in the galaxy…” was kind of clunky. Plus Rey’s line that went like “Master Skywalker, we need you to bring back the Jedi because Kylo Ren is strong in the Dark Side of the Force,” or something like that.
My least favorite line, though, is Rose calling Finn “a selfish traitor,” just because of who she’s talking to. Finn was a child soldier who’d been raised his whole life in a soulless military machine. He had never had a chance to live a normal civilian life. Then he goes and breaks out of his conditioning, runs away, and despite his fear of the First Order helps destroy Starkiller Base and save the Resistance, and then he even stands up to Kylo Ren himself.
After all that, Finn didn’t owe the Resistance anything, and he wasn’t officially a member, anyway. It was entirely within his rights for him to leave so that he could start his life over as a civilian. Rose’s admonishment seems like Rian Johnson wrote it with a different character in mind, one who hadn’t experienced what Finn had.
