In ANH and TESB, Luke had 1 failure using the force - lifting the X-wing. He did all the others the first time we see him try it (though not always on the first attempt, but that is the same with Rey).
He also failed at the Dagobah tree, and failed to contact Ben under Cloud City, and failed to mind trick Jabba, and failed to foresee the Rancor pit…
Luke stood his ground with Vader and several times drove him back. We didn’t really get to see the finish of Rey and Kylo’s first first fight because the breaking up of the planet separates them.
That’s like saying we don’t get to see the end of Luke’s fight with Vader because a vertical shaft has separated them, but I think it’s clear each time who came out of it unscathed and standing.
The second time, they don’t actually fight, except while trying to grab the lightsaber, which breaks in two. So Rey hasn’t exactly had a string of unqualified successes. If you really watch both films, you can see her many failures. But if you are concentrating on her force use in saying she never failed, then you have to look at Luke and how he rarely ever failed either.
All three of Luke’s final confrontations in the OT would have ended with him dying had it not been for sudden and fortuitous aid. Also, if you consider Qui-gon the main character of TPM, all of the prequels end with the hero being horribly beaten. Rey has held her own in each of her final confrontations and has basically saved herself each time.
At the end of TESB, Luke quickly goes from the horror of the revelation that Vader is his father to acceptance and then he gets a new hand and is smiling with Leia, who seems more upset than he is.
Smiling is a strong term.
At the end of TLJ, Rey, who was briefly elated by the success she and Chewy had in the air over Crait, is feeling dejected and wondering what the next step is.
There’s also the bit where she is all smiles as she reunites with BB-8 and Poe.
Luke is already executing a plan to rescue Han, but Rey has no plan. So yes, please delineate how Rey just has it so easy. I don’t see it that way and I fail to see how you can if you take into account all that we see on screen.
I’m all for viewing the sequel trilogy as drama more than action, so the relative power of the hero to the villain really doesn’t bother me that much. However, I do take exception to a misrepresentation of these movies.
