Okay so the "Rose Tico was sidelined and it's wrong!" people are officially the whiniest b*tchiest star wars fans. Worse than any whining about Rey. Every article talking about the movie seems to cry about this and every day I see new news articles completely dedicated to it.
Here is the thing: No, she had 10 minutes of screen time in TLJ. She is not a main character. She never was. She is not a good character. If she was sidelined because of fan complaints then good. They should be catering to what fans want not critics and sjw's.
