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). 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. 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. 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. 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. 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.
