Trained is a stretch and a half. Rey is tough and she can scrap... with random thugs on some dusty backwater planet.
Kylo Ren is a powerful and experienced user of the Dark Side of the force. He is the leader of the Knights of Ren, a group even Snoke seems to hold in high regard. He goes into battle with only a lightsaber and is untouchable. This guy by all accounts should be nigh untouchable to Rey but he gets clowned during the interrogation scene and rekt in their duel. It's shitty.
I think she only screwed up with the safety on the blaster. After that she took out a bunch of troopers. Not really a big deal to me since troopers get owned by everyone.
You can lob accusations all you want, but so long as you continue to ignore the actual arguments simply because you don't like them, you'll be arguing in bad faith.
Arguing that in bad faith because I reject the intentional misrepresentation of what happened in that movie?
Rey used straight up martial arts moves on her attackers.
Ren is deliberately portrayed as more sloppy and volatile, and is obviously extremely conflicted about what he is doing. His mind is in turmoil and his self-control is weak.
No where do we see anything to suggest that Ren is necessarily a better fighter than Rey. His only verified advantage is better knowledge and control of his force powers.
Ren was very seriously wounded several times (would which would each take a normal person out of thrig It or kill them) before fighting Rey in a type of combat that suits her strengths. And Rey only triumphs because of tapping into what are obviously incredibly strong latent force powers and used sheer force of will to overpower Ren after he had out-fought her.
She is either just much more inherently powerful in the force than Ren, or just has better focus and menal peace to wield the force, or only just barely edged him out due to his injuries, or some combination of the three.
The story comes right out and tells you that Rey doesn't know how to use a blaster but won't admit it, and she doesn't even know how to hold it when Han gives it to her. And she fucks up again when trying to shoot with the safety on. The best she can do is spray and pray but let's not let that get in the way of a trumped up Mary Sue accusation.
