bruh.....not everyone views beauty the way u want it to be ...stop acting childish
there are a lot of factors at play but mostly exposure, as in a main actress in a bigger budget/production gets way more exposure and media attention than a support in a lower budget, and is going to be way more popular and have more followers as a result, whether she is better looking or not. Most of the time the supports are better looking than the mains but they can go unloved.
