The Good Place aired its final episode in 2020, and I’m certain the sitcom still has one of the best character redemption arcs on television. The show revolves around Eleanor Shellstrop, a selfish character who wakes up in “the Good Place” after she dies. She assumes it must have been a mistake, as she was a terrible person during her time on Earth. This is why she enlists Chidi, a professor of ethical philosophy, to teach her how to become a good person who is worthy of remaining in the Good Place.
