People finding out that she couldn't "act" killed her career
Let's go back to 2015. Yes she starred in some kids series a few years before but in 2015 she had an "influencer" career that was not acting based. Remember when the "white lady" made fun of her braids and people lost it? Zendaya was the media darling back then that could not be touched.
About a year later she released a clothing line that people loved and continued to model for instagram.
But then in 2019... "Euphoria" was released. It became obvious she could not act herself out of a paper bag and really wasn't that good looking without makeup and glamor to be honest. The second season had other actresses receive fame and praise over her while she faded.
I mean . Damn. I feel kind of bad for this woman.
