The arrival of Star Wars: The Last Jedi has led to a lot of new reveals, especially coming from the bonus documentary The Director and The Jedi. In the special feature, Rian Johnson talks about developing the character of Rose Tico, and making her fit into the world.
Johnson said (via Phil Szostak):
"When I wrote that character of Rose, she was genuinely a nerd, like someone who I would have actually hung out with in high school. She felt like a character who didn't belong in a Star Wars movie. And it appealed to me."
For some reason, Rose came out to be one of the most divisive characters from The Last Jedi. Though some love her attitude and spunk, a lot of people thought that her arc with Finn was a bit forced, and her act of saving Finn was hypocritical to what she says about ‘not fighting what we hate, but saving what we love.'
Personally I like Rose's character, and I would love to see more of her in Episode IX. She's basically a female version of Lando Calrissian; introduced in the second movie, and becomes part of the main cast of characters.
Star Wars: The Last Jedi is now available on digital and hits Blu-Ray on March 27.
