TLJ screwed this all up for me. She didn’t get any training from Luke, but apparently she’s a full-blown Samurai now. I could have lived with that, but the scene with the rocks was stupid. Yoda’s lifting Luke’s X-wing in TESB was a demonstration of mastery. Rey’s tossing CGI boulders around like styrofoam was purely 'cos she can. Hell, she was as surprised as I was!

I think there’s a key difference between ESB Luke and Rey here, and I believe you can transfer what you liked about TFA’s Rey to this film. Back in the days I also defended Rey’s progression in TFA, I pointed out that Rey developed a skill more valuable than combat prowess. What was that skill? Patience. All those years spent in isolation on Jakku, that meant many days and nights of being alone. She was also willing to wait hard long years for her supposed parents to return. So with this skill, this served as a trait that allows Rey to really soak in her surroundings, to open herself up to the light, the darkness, the life, and decay, as seen in that mediation sequence. Even in TFA, she paused for that brief moment with Kylo Ren in that duel in order to form a close bond with the Force.

So as it stands, I still don’t exactly have issues with Rey’s fast Jedi progression. Luke was pretty impatient for two movies. You could tell he wanted the Jedi Knight status NOW. Yes, Luke grew up a on a nearly desolate desert planet, but his life was much ‘easier’ in comparison to nearly every day being survival for food and shelter, alone, that Rey faced.

What I DO have an issue with is that Rey has very little conflict character wise. Her fast Jedi leveling-up would be fine if she had stronger inner conflict.
