Luke is a **** up throughout the original movies.
- Sandpeople beat him up and knock him out (Obi-Wan saves him)
- Cantina patrons rough him up (Obi-Wan saves him)
- he almost gets blown up by Vader (until Han Solo shows up and saves him)
- Han mocks him because Luke thinks he's a hotshot pilot when he's really not
- can't deflect remote bolts, gets shot in the leg/ass which Han also mocks
- he can't communicate with R2 without a translator
- Leia saves him in a rescue mission for HER, even makes fun of him
He's whiny, vulnerable, impatient, can't lift X-Wings, gets his hand chopped off, etc. etc. In original treatments and deleted scenes he was known as "wormy" and Biggs is the only one that liked him.
Compare that to Rey who would have beaten up the Sandpeople and cantina patrons single-handedly with her staff (like she did with the Jakku thugs). Knows the Millennium Falcon better than Han and Chewie (much to Han's own surprise). Quips that she doen't need no blaster. Can use the force and wield a lightsaber with ease by just thinking hard about it. Expert pilot, expert marksman (the Troopers right before the Kylo Ren scene). Can communicate with all droids and aliens. Gets a job offer from Han and knows pretty much everything but why she was abandoned and how/why she has all these new found powers (da force is calling to her).
It took Luke 3 movies to go from this,

And even then he gets wrecked by the Emperor and only survives because of the love of his father . . . or something.
