Actually, it's the truth.
No, it's not. Remotely. Once more for posterity -
Luke fails throughout the movie. He screws up constantly. He is rescued from danger by other characters on numerous occasions:
Obi Wan saves him from the sand people.
Obi Wan saves him from stormtroopers.
Obi Wan saves him from the bar toughs.
Leia saves him (and Han & Chewie) from their poorly thought-out rescue attempt.
Han saves him from Vader.
Luke is given exactly ONE unique or special skill in the movie - he's a good pilot. This is established in dialogue on several occasions and therefore doesn't just come out of nowhere when Luke (somewhat improbably) takes the stick of an X-Wing during the Death Star assault.
When Luke is first aboard the Falcon - which is Han's ship - Han tells Luke to sit down, shut up and get out of the way.
Luke is shown to use the Force exactly once, after receiving hands-on training from Obi Wan. He can't just do it...just cuz.
Rey never makes any mistakes. She never needs anyone's help. In fact, she gets irritated when Finn tries to help her.
Rey has numerous special skills. She is an expert in hand-to-hand combat. She is an expert mechanic. She is an expert pilot. She speaks Wookiee and she speaks droids (um, why, exactly??)
When Rey is first aboard the Falcon - which is Han's ship - she flies it like a pro. Later, she shows that she knows more about how to fix the Falcon than Han or Chewie.
Rey never needs anyone to rescue her. When she's captured, she frees herself, even though her friends are risking their lives to try to save her.
Rey is never given any force training at all, yet she uses the force on several occasions. She uses a mind trick (how does she even know that's a thing that's even possible?) She uses telekinesis. She uses it for enhanced combat, besting a Force/lightsaber expert in a duel.
Now, I think
some of this is perfectly okay and is justified. Just as Luke is allowed to have one special skill, some of Rey's skills are organic and earned. She obviously wound need to be able to defend herself on the dangerous, hard-scrabble world of Jakku. She makes her living scavenging parts and tinkering on ships, so I buy that she knows her way around a starship.
But the cumulative result of ALL of her special skills, combined with the fact that she's never, not once, permitted to screw up or need help to appear vulnerable, makes her into a flat, superheroic character who isn't dramatically or emotionally accessible. She's perfect. Perfect is the opposite of drama. It's boring. It's childish. It's bad writing.
If the Sue fits...
