ABC’s newest sitcom “Abbott Elementary” has quadrupled its rating since its debut. But CNN reporter Lisa Respers France says the show’s creator Quinta Brunson is bringing more than laughs — she’s teaching us something. “Abbott Elementary” is about a group of dedicated teachers in Philadelphia who are dealing with a lot of the same issues real teachers face across America. Brunson is well known for her previous role on “A Black Lady Sketch Show” and the self-produced Instagram series “Girl Who Has Never Been on a Nice Date.” Brunson’s new show also stars Tyler James Williams and Sheryl Lee Ralph.
