Rey Palpatine (Star Wars)

Rey is the main protagonist of the Star Wars Sequel Trilogy (Ranging from episodes VII, VIII, and IX). Ever since she was on the big screen, there was a huge controversy.

Why She Sucks
However, this might have happened because Kylo Ren is mentally unstable and was injured by Rey's friend, Finn.
 * 1) Rey is a Mary Sue, she learned the force by an instant as opposed to Luke Skywalker where he had to train during all three of the original films (IV, V, and VI) to become a Jedi Master.
 * 2) Continuing with the Mary Sue thing, in Star Wars VII, she wounded Kylo Ren in just a couple hits when yet comparing Rey's fight to Luke Skywalker's fight with Darth Vader, it took several hits for Luke Skywalker to take down Darth Vader.
 * 3) Speaking of Luke Skywalker, she made him look awful.
 * 4) She was supposed to be the main protagonist of the sequel trilogy of Star Wars (Similar to how Jar Jar Binks was supposed to be the comic relief of the prequel trilogy), however, they failed miserably; Rey lacked a personality.
 * 5) Rey and Kylo Ren have a strange relationship despite the two hating each other, especially the latter.

Redeeming Quality

 * 1) Some fans still tend to like her despite her lack of personality and flaws.
