Ah, yes. You've seen her fairly cute mug all over the net.
And some people are irate, for whatever reason. Let me explain why JJ went way too far with Rey in Star Wars, and showed that today's feminism seems to mean "Girls can do everything better than guys".
In the course of one movie, Rey goes from being a scavenger on a hell hole world, to showing, mainly... she--
1. Is a skilled pilot, who can jump in the Millenium Falcon and expertly fly it against Imperial Tie pilots without hesitation or training or practice.
2. Is a skilled Jedi who can use mind tricks and manipulate the force with literally Zero training
3. Is a master fighter who literally grabs a lightsaber and takes on a trained, evil fighter who apparently is so skilled he murdered all of Luke Skywalker's jedi pupils. Apparently by himself?
Let's compare her to a legendary Jedi from the earlier Star Wars movies, Obi-Wan, to show the female vs male standard here. (Neither Obi-Wan or Rey are magical "chosen ones" so it is a good comparision.)
Let's look at Obi-Wan Kenobi's achievements.
Phantom Menace: Obi-Wan is roughly the same age as Rey, give or take, but he has spent his entire life being trained as a Jedi, and is the apprentice of Jedi Master Qui-Jon.
He is a skilled lightsaber fighter, and can use the force. He also gets told repeatedly he has much to learn, gets snubbed by the council when he asks to try out for the Jedi Trials, and literally wins his duel with Darth Maul by pulling a trick out of a hat right before he was going to get killed.
Attack of Clones: Obi-Wan is then a full Jedi Knight, far above Rey in training. A 30-something year old man who is a professional and a lifelong warrior.
1. He shows skill in tracking, and takes down a bounty hunter who tries to kill him in a seedy bar.
2. He gets his ass handed to him in close combat by a bounty hunter and his kid, neither of whom are jedi/sith.
3. Then barely survives and escapes Jango Fett in a space skirmish.
4. Gets ambushed and captured by *droids* on the Federation's main hideout, Geonosis.
5. Goes up against Count Dooku and gets his ass handed to him.
Okay, let's look at Revenge of the Sith:
Obi-Wan is even more of a skilled, experienced warrior Jedi.
1. He is a skilled pilot, but his ship gets ruined by tiny droids rather quickly.
2. He then takes on droids very well, and later Clone Troopers very well.
3. He *again* gets his ass handed to him by Count Dooku.
4. He goes up against General Grievous, not force sensitive, and literally only survives thanks to luck. When Grievous grabs him and lifts him up, instead of ripping the Jedi in two or crushing his throat, Grievous literally throws him next to a blaster.
5. Obi-Wan then fights Anakin and wins solely by being the calm, cool fighter and waiting for a moment when brash, aggresive Anakin made a mistake.
So let's be real here on the male vs female standard. One author I read claimed it was only because of sexism that anyone protested Rey's skills. The reality is that Rey, as an untrained scavenger, literally has MUCH greater success both as a pilot, and a fighter than Obi-Wan Kenobi himself achieves, even though Obi-Wan was literally trained as a Jedi, and a warrior, his whole life.
Untrained scavenger Rey takes on Kylo, who slaughtered every Jedi pupil Luke Skywalker had, and flies the Falcon as well as Han Solo.
Jedi Knight Obi-Wan literally has his ass handed to him by everyone from droids on Geonosis, to a bounty hunter and his kid both in close combat and in space, to Count Dooku on two occassions...
Can we see the feminism and grrrll power at work here?
