Teenage girls with secret superpowers seem to be all the rage on Netflix, and their most recent coming-of-age series is no exception. “I Am Not Okay With This” follows 17-year-old Sydney Novak (Sophia Lillis) as she struggles with her father’s recent passing and the awakening of her strange superpowers. The series is based on a graphic novel of the same title by Charles Forsman, who created the source material for another Netflix hit, “The End of the F***ing World.” It also shares producers with “Stranger Things.”
