I already told you.
You can go back and make Kylo’s character weak, and have him masquerade and pretend to be stronger than he really is, and that’s fine. Rey can beat him that way because he’s just a wannabe.
You can make Kylo’s character strong, but then Rey can’t beat him at the end because she’s not strong enough herself. She needs to be saved somehow.
You can make the story self-contained, and have Rey’s character grow in a believable manner, to the point she is strong enough to beat an already strong Kylo at the end of the movie.
The original Star Wars was a combination of #2 and #3. Our perception of Luke’s strength and abilities grew over the course of the film, to the point where he was able to pilot his X-wing down the trench and fire the shot that blew up the Death Star. But he was also saved by Han, otherwise Vader would have killed him.
What you cannot do is have an inconsistent story and ending. You can’t have Kylo be a badass, and Rey is untrained, and then she wins at the end for no reason other than someone decided “welp, it would be better if the good guys win”. The good guys winning is fine, but you have to go back and do the hard work in the other 90% of the story to make it believable. You need Story A to go with ending A. You can’t put story B and Ending A together and make it work.
I don’t see it as inconsistent and I am probably going to leave this discussion, as it is not getting anywhere and you seem to be ignoring my two main points:
- The ability to do cool magic tricks don’t necessarily mean the character is really all that powerful fighter.
- Even a powerful fighter can be defeated after he takes an arrow to the knee.
NO THATS NOT CONSISTENT WITH THE INTERNAL LOGIC SET UP BY STAR WARS BUT ALSO TFA WAS TOO MUCH LIKE STAR WARS BUT ALSO NOT ENOUGH LIKE STAR WARS ARGLEBARGLE
