the more i think about the movie, the more i process it, and the backlash, the more i love what they did. i'm curious and excited about what comes next, provided the whiny fan-babies don't ruin it all. i mean, shit, even if TLJ was a pure shitshow, it's a hell of a lot better than what's going on over in DC-movie land. the third lesson (actually, wait, internet sleuthing has determined that it is not in fact the third lesson. but merely a thing that happened and then she left, presumably before receiving the third lesson. but it's still a thing that happened between luke and rey) is described in the book; pretty sure it's not in the movie. i read it literally just last night. haven't checked to see if its in any deleted scenes anywhere (internet sleuthing confirms it is a "deleted scene"). spoiler alert: some boats head towards the island. luke tells rey that it's raiders coming to attack the caregivers; explains that he allows it to happen, as any true jedi knight would - allow what is, to be, or some such. rey is incensed, angry, and desperate to help. she runs down the mountain, bursts into the village where the boats have already landed. and interrupts a party for the fishermen... fishergivers... carefishers...? fishing party... that just returned. luke catches up to her. and explains. what the resistance needs is not a husk of a legend, and old jedi knight. but a fierce, determined warrior ready and willing to take on the enemy and save the imperiled galaxy. this convinces rey what she already knew - that she would not rely on luke skywalker to save the galaxy, but must do it herself.
