This is just like, abjectly not true. At the end of ANH, Luke is told to "use the force" by Obi-wan. Which means, what exactly? He had no idea, because he'd had no training. But he did it anyway to make a nigh impossible shot by (force aided) instinct. This is no different from Rey. I think our familiarity with the old films has made it hard to recognize that Luke is doing some crazy shit really fast.
Within one minute of having a helmet put on to blind him, Luke is blocking multiple shots with a lightsaber. Blind! I mean, holy shit.
It feels different. Feeling an ephemeral wave of the Force and blocking 2-3 taser shots from a practice droid, and making what was basically a sniper shot with no scope...just feels different that picking up a light saber and taking down someone who is clearly very skilled with the Force.
It would have been different had the film made it clear Kylo just wasn't that strong, but that's the opposite of what we saw - effortlessly suspending blaster shots in middair, sending people flying away or towards him, the mind torture - the film built him up as a talented Force user, and then, on top of that, revealed that he's actually a Skywalker.
People can talk about Kylo being injured with the blaster shot, but the reality is that his movement didn't seem to be impaired at all - he was moving around with grace, and was apparently well enough to throw in a few spin moves during the fight. And yet...after meditating, Rey literally beat his ass down, repeatedly.
It just didn't sit well with me.
