Sorry, Gwen, but that's not the reason why fanboys don't like Kylo.

First of all, Kylo Ren's descent to the Dark Side is pretty much poorly explained and makes him seem more of a petulant man-child than a torn, traumatized person who falls into despair. Say what you want about Hayden's acting, Anakin's fall from grace was far more poignant and well thought out than Ben Solo's. Simply put, Kylo and Rey are perfect avatars of the entitled, reactionary, and hypersensitive Millennial generation.

Second, not many fans like Rey because of how she's been portrayed as a Mary Sue. And no, that's not a sexist term, it's based on a character created in a Star Trek fanfiction called A Trekkie's Tale, which was a spoof of the Star Trek series. Lt. Mary Sue was total wish fulfilling fan fiction, not a well thought out character with depth. And there is a male version of Mary Sue. He's none other than Ensign Wesley Crusher from Star Trek: TNG, and quite possibly the most hated character in Star Trek history according to fans. Even Will Wheaton admits hating his character.

Unlike Luke, Rey was given abilities she shouldn't have. Luke went through three films and two mentors in the form of Obi-Wan and Yoda going from a novice who knew nothing about the Force and having to train using a floating drone while wearing a blast shield over his face during lightsaber training, to having to struggle to make his lightsaber fly into his hand to free himself from the ice cave and defeat the Wampa snow monster, to having Yoda teach him how to make rocks float(as well as R2D2) only to drop them the moment he's distracted, and then have Yoda humble him by lifting his X-Wing out of the swamp when Luke himself was unable to do it, to finally having the powers of a fully trained Jedi in the third film where he's now capable of doing all the things that Obi-Wan, Yoda, and Darth Vader can do. Luke goes through the entire "hero's journey" which conveys depth and growth to a character.

But Rey? In one film, she feels a connection to Luke's lightsaber(which is never explained), learns how to do the old "these aren't the droids you're looking for" mind-pushing trick without even so much as having seen someone do it let alone be taught how to do it, and knows how to make the lightsaber fly into her hands and away from Kylo(who's had years of training) and become a skilled swordswoman even though she's never once held a lightsaber in her hands in her life.

Now, Ellen Ripley from Alien and Aliens was a total badass and a REAL action heroine. She's from the 1980s, so naturally she's better. Look at the difference and you'll know why fans love Ripley but dislike Rey.
